What must be added to 203 to get a number whose digits are reversed of the given number?
Solution:
The number obtained by reversing the digits of 203 = 302.
∴ Difference = 302 – 203 = 99
Hence, the required number is 99.

75 cm
1.5 m = 1.5 × 100 = 150 cm
75 : 150 = 75/150 = 3/6 = 1/2

5 Hundreds + 3 Tens + 8 Ones + 4 Tenths
= 5 x 100 + 3 x 10 + 8 x 1 + 4 x 1/10
= 500 + 30 + 8 + 4/10
= 538 + 4/10 = 538.4

Vijay bought vegetables weighing 10kg.
Out of this 3kg 200g onions , 2kg 300g tomatoes and the rest is potatoes.
The weight of potatoes = 10 kg - ( 3.200 + 2.300)
= 10.000 - 5.500
= 4.500
= 4 kg 500 g

BIOT-SAVART LAW:
- We already know now that current carrying conductor generates magnetic field around themselves. Biot-Savart law just mathematically states the intensity of this magnetic field at a point.
- According to the Biot-Savart law, magnetic field dBdue to current element idl, at a pointP situated at distancer from the current element idl,is:
i) directly proportional to the current element idl, ii) directly proportional to the sine of the angle (θ) between current element and r, and iii) inversely proportional to the square of the distance r between current element and the point
dB∝idl (sinθ)/r2
dB = (μo/4π)×idl×(sinθ)/r2
dB = idl × r / r3
Here proportionality constant is μo/4π = 10-7Tm/A, and μois the permeability of free space (vacuum)

An electric dipole is defined as a couple of opposite charges q and –q separated by a distance d. By default, the direction of electric dipoles in space is always from negative charge -q to positive charge q. The midpoint q and –q is called the centre of the dipole. The simplest example of an electric dipole is a pair of electric charges of two opposite signs and equal magnitude separated by distance.

Electric field is a force produced by a charge near its surroundings. This force is exerted on other charges when brought in the vicinity of this field.
- SI unit of electric field is N/C (Force/Charge).
- Electric field due to a charge at a point is the force that a unit positive charge would experience if placed at that point.
- The charge generating electric field is called source charge and the charge which experiences this field is called test charge. Practically, to keep source charge undisturbed due to the electric field of test charge, the test charge is kept infinitely small.
- Since F(Force) is proportional to q (Charge), the electric field is independent of q but depends on r (space coordinates).
- The electric field is symmetric in spherical coordinates.
