CBSE Board | Homework Help

For Gauss's law we have to prove 1/£° time of charge ..... So We have E•dS where as E is electric field intensity and S is surface area of sphere now We have studied that E=kq/r^2 And k=1/4π£°(1 by 4 pie epsilon not) Now put value of both E and s in E•ds S=4πr^2 (4 pie r squ•) Now 4πr^2 and 4πr^2 will be cancel out and you will get 1/£°(1 by Epsilon not) Note:- for removing d you have have to take cos 0 because when you will draw a circle you will get to know why i took cos 0°(cos0°=1)

Reading is one of the best qualities that an individual should have. Books are often known to be your best friend for a specific reason. So, it is essential to build a good reading habit within oneself. We must all read daily for at least 30 minutes to enjoy the knowledge gained from reading. It gives a reader great pleasure to sit in a quiet place and enjoy reading without any disturbance. Reading books as a hobby is the most enjoyable experience a person can have. Books contain vast amounts of information which can only be learned by reading them.

Satya Nagar Colony Bhubaneshwar, Orissa The SHO Police Station Satya Nagar Bhubaneshwar, Orissa Dated: 30 Nov, 2020 Subject: Neighbours repeatedly flouting quarantine rules Sir, I want to bring to your attention that some of my neighbours are continuously flouting the quarantine rules even after being tested covid19 positive. Two members of the infected family are moving openly and that too without a mask. The second floor of House no. 39 in the opposite street is occupied by two college boys living as paying guests. Many outsiders keep visiting these boys. It can be dangerous in this tough time of highly infectious coronavirus disease. The owner of the house is a couple of senior citizens who are worried about their health. I request immediate intervention from the police so that this disease can be contained at the right time and residents can feel safe and secure. Yours Sincerely, Tabassum

Cotton is harvested when the pods mature. Then, the cotton fibre is taken out, pods and seeds separated from it. The cotton thus obtained is shipped to spinning mills, where yarn is made. The yarns are then bleached with chemicals and dyed with dyes or pigments. Thereafter, the yarn is sent to textile mills for being woven into fabric. If the yarn had not been bleached and dyed at the spinning mill, an off-white fabric is obtained; this is called grey fabric and it is now bleached and dyed. Once the fabric is woven, it is shipped to distributors or wholesalers, who in turn sell it to retailers. The retailers then sell it to customers like us. We buy cloth as per our requirement and get it stitched by a tailor. Eventually, the shirt is collected from the tailor and finds its way into our wardrobe. In the case of readymade shirts, the function of the tailor is eliminated. The fabric at the textile mill is sent to an in-house garment manufacturing unit or to an unit outside for making shirts, which when done are shipped to shops or accredited showrooms for sale to customers like us.

The postmaster was expressed by Lencho's faith in God. In one not to shake Lencho's faith in God he decided to reply the letter. But when he read the letter, he realised God that he needed more than pen and ink. He needed the money earnestly to sow the crop that had been completely ruined by the hailstorm and also to feed his family until the next crop. The postmaster stuck to his resolution to help and reply Lencho's letter. So,he collected money from his colleagues and friends as a part of his salary but could collect 70 pesos and not 100. He put money in an envelope addressedto Lencho and with it a letter containing only a single word as a signature :God, implying that none else but God was sending him the money
