List of top Physics Questions on electrostatic potential and capacitance asked in MET

A conducting sphere of radius R is charged to a potential of V volt. Then the electric field at a distance \(r(>R)\) from the centre of sphere would be :

A body of specific heat \(0.2\ \text{kcal/kg}^\circ\text{C}\) is heated through \(100^\circ\text{C}\). The percentage increase in its mass is

A charge of \( 10^{-9} \, \text{C} \) is placed on each of the 64 identical drops of radius 2 cm. They are then combined to form a bigger drop. Its potential will be:

In countries nearer to polar region, the roads are sprinkled with $CaCl_{2}$. This is

A charge is rotated in a circle of radius $r$ around a central charge. The work done is:
