A test charge q is made to move in the electric field of a point charge Q along two different closed paths. First path has sections along perpendicular to lines of electric field. Second path is a rectangular loop of the same area as the first loop. How does the work done compare in the cases?

A test charge q is made to move in the electric field of a point charge Q along two different closed paths. Fig. First path has sections along and perpendicular loop of the same area as the first loop. How does the work done compare in the two cases?

A point charge q is placed at the origin. How does the electric field due to the charge vary with distance r from the origin?

Show that the work done in moving a unit charge along a closed path is zero.

In the electric field of a point charge q, a certain charge is carried from point A to B, A to C,A to D and A to E. Then the work done

Show that the path followed by a charged particles moving in a direction perpendicular to the electric field is parabolic?

Prove that the work done in moving a unit charge along a closed path in an electric field is zero?

A test charge q is moved without acceleration from A to C along the path from the point A to B and then from B to C in electric field as shown in fig. Calculate the potential difference between A and C.

A particle with charge q moving with a velocity v in the plane of the paper enters a uniform magnetc field B, acting perpendicular to the plane of the paper. Deduce an expression for the tie period of the charge, as it moves in a circular path in the field. Why does the kinetic energy of the charge not change, while moving in the magnetic field?

A test charge q is moved without acceleration from A to C along the path from the point A to B and then from B to C in electric field as shown in fig. At which point( of the two) is the electric potential more and why?
