Question

A one coulomb charge is placed on an insulated stand at the centre of a spherical conductor of radius $1\,m$. The sphere is given a charge of $1\,C$. The electrostatic force experienced by the charge at the centre will be :

• A. $zero$
• B. $1\,N$
• C. $9\times10^9N$
• D. none of the above

Answer 1

Answer: (A)

$zero$

Answer 2

Electric field inside the charged conductor is zero. So, the force on the charge inside it is also zero.
