A charge is being induced to a sphere with the help of another charged sphere. The extent of induction increase if ____________
a) The distance between the sphere increases
b) The distance between the sphere decreases
c) The two spheres are kept in contact with each other
d) Remains same irrespective of the distance between the spheres
Explanation: The extent of induction increases if both the spheres are kept close to each other because more electrons in the uncharged sphere are attracted or repelled by the charged sphere, so the extent of induction increases.
