Question

the electric field at a distance 10cm from the centre of a uniformly charged non conducting sphere of radius 5cm is E. Then at a distance 2.5cm from centre electric field will be​

Answer 1

Answer:

2E

Explanation:

The sphere is non conducting so there will be electric field inside it

Electric field outside is given by - KQ/R^2 where R is 10cm

Electric field inside is given by - KQx/r^2 where r is radius 5cm and x is distance from the center 2.5 cm

Put the values and divide you will get the answer

2E
