Given below are two statements : One is labelled as Assertion $A$ and the other is labelled as Reason R
Assertion A : Two metallic spheres are charged to the same potential One of them is hollow and another is solid, and both have the same radii Solid sphere will have lower charge than the hollow one
Reason R : Capacitance of metallic spheres depend on the radii of spheres
In the light of the above statements, choose the correct answer from the options given belows
NaOH is deliquescent
An electric dipole is a pair of equal and opposite point charges -q and q, separated by a distance of 2a. The direction from q to -q is said to be the direction in space.
p=q×2a
where,
p denotes the electric dipole moment, pointing from the negative charge to the positive charge.
