The ratio of the sum of m and n terms of an A.P is m square : n square . Show that ratio of m th and n th terms is 2 m-1: 2n-1

Posted by Simranjeet Kaur 6 years, 3 months ago

Gaurav Seth 6 years, 3 months ago

Sum of m terms of an A.P. = m/2 [2a + (m -1)d]
Sum of n terms of an A.P. = n/2 [2a + (n -1)d]

m/2 [2a + (m -1)d] / n/2 [2a + (n -1)d] = m:n

⇒ [2a + md - d] / [2a + nd - d] = m/n
⇒ 2an + mnd - nd = 2am + mnd - md
⇒ 2an - 2am = nd - md
⇒ 2a (n -m) = d(n - m)
⇒ 2a = d

Ratio of m th term to nth term:
[a + (m - 1)d] / [a + (n - 1)d]
= [a + (m - 1)2a] / [a + (n - 1)2a]
= a [1 + 2m - 2] / a[1 + 2n -2]
= (2m - 1) / (2n -1)

So, the ratio of mth term and the nth term of the arithmetic series is (2m - 1):(2n -1).

What is range of nuclear force

Posted by Shivani Nag 6 years, 3 months ago

CBSE > Class 11 > Physics

1 answers

Mehak Gautam 6 years, 3 months ago

The weak nuclear force has a limit in range of only 10 to -18th meters. This means that the carrier particles must indeed have mass. The weak nuclear force is found to have three carrier particles, two W bosons, one charged -1 and one charged +1, and the electrically neutral Z boson.

What do you understand by error of measurements? Discuss briefly the various types of error

Posted by Netik Verma 6 years, 3 months ago

CBSE > Class 11 > Physics

1 answers

Mehak Gautam 6 years, 3 months ago

An error or fault can be described as the disparity between the calculated worth and the exact worth. For instance, if the two machinists use a similar instrument for discovering the errors in measurement, it is not required that they may acquire the related outcomes. But, there will be a slight variation between both the measurements which is known as an error. The errors in measurement may happen from the various sources which are generally categorized into the following types. These are clarified beneath in details. Systematic Errors Gross Errors Random ErrorsThese types of systematic errors are generally categorized into three types which are explained below in detail. Observational Errors Environmental Errors Instrumental Errors Systematic Errors
