A Cat's skin aquires ___________ charge when rubbed with ebonite rod.

When a glass rod is rubbed with silk, it

What kind of charges are produced on the glass rod and the silk, when rubbed with each other.

Figure shows a rod of length L which is uniformly charged with linear charge density lambda kept on a smooth horizontal surface. Right end of rod in contact with a vertical fixed wall. A block of mass m and charge q is projected with a velocity v from a point very far from rod in the line of rod. find the distance of closest approach between the block & the left end A of the rod.

If a body is charged by rubbing it , its weight

Two bodies are charged by rubbing one against the other. During the process, one becomes positively charged while the other becomes negatively charged. Then

An electrometer consister of a fixed vertical metal bar OB at the top of which is attached a thin rod OA which gets deflected from the bar under the action of an electric charge (fig.). The rod can rotate in vertical plane about fixed horizontal axis passing through O. The reading is taken on a quadrant graduated in degrees. The length of the rod is l and its mass is m. what will be the charge when the rod of such an electrometer is deflected through an angle alpha in equilibrium. Find the answer using the following two assumptions : The charge on the electrometer is equally distributed between the bar & the rod and the charges are concentrated at point A on the rod & at point B on the bar.

When an ebonite rod is rubbed with wool, the rod becomes negatively charged.

When an ebonite rod is rubbed with wool, the rod becomes negatively charged. How?

Two identical metallic spheres X and Y with electrons supported on insulating stands and placed in contact. What kind of charges will be daveioped on X and Y when a negatively charged ebonite rod is brought near X?

Usually it is the negative charge that is transferred when two bodies are rubbed together. Can you explain why?
