Two metal plates A and B are connected to cell of emf 2V is shown in the figure
A charged particle starting from rest moves in the opposite direction of electric field, is it an electron or proton?

Two metal plates A and B are connected to cell of emf 2V is shown in the figure Calculate acceleration of an electron moving from B to A

Two metal plates A and B are connected to cell of emf 2V is shown in the figure br Redraw the diagram and draw lines of forces to represent electric field.

A metal sphere of radius R carrying q (+ve) charges is shown in the figure. br Derive the strength of electric field at a distance r from the centre of sphere.

A rectangular conductor of length and area of cross section and electron density .n, is shown below. . Under the application of an electric field do all the electrons move in a same direction? Explain.

An electric charge q is moving with a velocity v in the direction parallel to the magnetic field B. The magnetic force acting on the charge is
