Question1

An electron accelerated from rest through a voltage of 400 V enters a region of constant magnetic field. If the electron follows a circular path with a radius of 30 cm, what is the magnitude of magnetic field?

Question2

A pair of oppositely charged parallel plates is separated by 4.83 mm. A potential difference of 505 V exists between the plates.

What is the magnitude of the force on an electron that is in the region between the plates at a point accurately 2.52 mm from the positive plate?

Question3

Two bodies fall freely from different heights & reach the ground concurrently. The time of descent for the first body is t1=2sec. & for the second, t2=1sec.

At what height was the first body situated when the other began to fall?
