Question

Statement - 1: No work is done in taking a small positive charge from one point to other inside a positively charged metallic sphere while outside the sphere work is done in taking the charge towards the sphere. Neglect induction due to small charge.

Statement - 2: Inside the sphere electric potential is same at each point, but outside it is different for different points.

a) Stmt 1 and 2 are true, stmt 2 is the correct explanation
b) Stmt 1 and 2 are true, stmt 2 isn't the correct explanation
c) Stmt 1 is fals, stmt 2 is true
d) Stmt 1 is true, stmt 2 is false

URGENT PLEASE!!!

Answer 1

Hello friend :-)

According to your question

Statement 1 says => No work is done

in taking a small positive charge from

one point to other inside a positively

charged metallic sphere while

outside the sphere work is done in

taking the charge towards the

sphere. Neglect induction due to

small charge.

So I think Since no net charge is

enclosed in the sphere therefore the

electric field inside the sphere would

be zero.

Now come to second statement =>

Inside the sphere electric potential is

same at each point, but outside it is

different for different points. I think

The potential of any point of the

sphere is zero. For this to occur a

charge must induce on the surface of

sphere but it's not equal to −Q.

Rather it's −RQ/d −RQ/d , where R is

radius of sphere and dd is distance

between center of sphere and

charge Q

By the above reasons I think

statement Statemen 1 and 2 are true,

statement 2 isn't the correct

explanation

Hope this helps you
