Chapter 1 – Electric Charges and Fields

Two identical pendulums A and B are suspended from the same point. Both are given positive charge, with A having more charge than B. They diverge and reach equilibrium with A and B making angles θ1 and θ2 with the vertical respectively. Two identical pendulums A and B are suspended from the same point. Both [...]

Two negative charges of unit magnitude and a positive charge q are placed along a straight line. The charge q is placed between negative charges as such the system of charges is in equilibrium. This system is in a third equal and similar charge is placed. Then third charge In the midway between two equal [...]

As shown in the adjoining figure two charge particles each having charge q and mass m and d distance apart from each other. If two particle in equilibrium under the gravitational and electric force, then the ratio q/m is As shown in the adjoining figure two charge particles each having charge q and mass m [...]

In the midway between two equal and similar charges, a third equal and similar charge is placed. Then third charge a third equal and similar charge is placed. Then third charge In the midway between two equal and similar charges December 5, 2020 Category: Arihant Physics by D.C Pandey , Chapter 1 - Electric Charges [...]

A particle with positive charge Q is held fixed at the origin. A second particle with positive charge q is fired at the first particle and follows a trajectory as shown (assume region to be gravity free). 1) show electrostatic attraction while pairs (2 2 3% 4 5) show repulsion. There ball 1 must be [...]

Two identical charged spheres are suspended by strings of equal length the strings make an angle 30 degree with each other. When they are immersed in a liquid of density less then the density of the material of the spheres. 1) show electrostatic attraction while pairs (2 2 3% 4 5) show repulsion. There ball [...]

Two metallic spheres carry equal charges. The distance between the spheres cannot be considered large in comparison with the diameters of the spheres. In which case, will the force of interaction between the spheres be greater? Two metallic spheres carry equal charges. The distance between the spheres cannot be considered large in comparison with the [...]

Five balls numbered 1 to 5 are suspended using separate threads. Pairs (1,2),(2,4),(4,1) show electrostatic attraction while pairs (2,3),(4,5) show repulsion. There ball 1 must be 1) show electrostatic attraction while pairs (2 2 3% 4 5) show repulsion. There ball 1 must be Five balls numbered 1 to 5 are suspended using separate threads. [...]

Two identical charged spheres suspended from a common point by two massless strings of lengths l, are initially at a distance d (d much less than l ) apart because of their mutual repulsion. The charges begin to leak from both the spheres at a constant rate. As a result, the spheres approach each other [...]
