Question

SYWOLONU.
A charge Q is uniformly distributed over the surface of a spherical shell
of radius R. The work done in bringing a test charge Q, from its centre to
its surface is
(A)
1 QQ
4ne,
R
(B)
1 QQ,
4Tɛ2R
QQ.
ER
Zero
(D)​

Answer 1

Answer:

answer is zero

Explanation:

because electric field inside a shell is zero. so no work is done in moving the charge from centre to the surface

Answer 2

The work done in bringing a test charge q from its center to the surface will be zero.

Explanation:

• In a uniform spherical shell, the electric potential acting on all points of the sphere will be always uniform.
• Therefore when a work is done to move a charge q from the external shell towards the center, then w=q (v2-v1), where v2-v1 is the difference between the potentials of the point which will be always equal to zero.
• Hence the work done will be also zero.
