the concept of potential is associated with both gravitational and electric fields because
the phenomenon of electrical induction is possible due to
one positively charged metal ball and one negatively charged metal ball of same nature and same size are presented in a perfectly non conducting atmosphere and are held fixed close to each other. What will the two balls try to do as soon as they are given their respective charges
a simple pendulum is constructed by suspending a metal ball from a ceiling by tieing it with a light inextensible string. It is now set into oscillation. As soon as it is set into oscillation it is placed above a floorwhich is positively charged , in a perfectly conducting atmosphere. Now as time passes the time period T ofof the pendulum is noted very accurately. It is found that T
in a capacitor the charge on the capacitor is of positive nature and one of the plates is earthed. What will be the nature of the charge on the facing end of the earthed plate
consider the two plates of a capacitor. They are connected to the two terminals of a battery. However, the positive plate is larger in size than the negative plate which is now earthed through a wire. Now consider a plane surface through which that wire passes. Now this plane surface is rotated anticlockwise along its axis i.e. along the wire that passes through it. We observe that
