A proton accelarted by a potential differnce `V` gets into the unifrom electric field of a paralallel-plate capacitor whose plates extended over a length `l` in the motion direction. The field strenth varies with time as `E = at`, where `a` is a constant. Assuming the proton to be non-relatistic, find the angle between the motion directions of the proton before and after its fight throgh the capacitor, the proton gets in the field at the moment `t = 0`. The edge effects are to be neglected.

A proton of mass m and accelerated by a potential difference Vgets into a uniform electric field of a parallel plate capacitor parallel to plates of length 1 at mid-point of its separation between plates. The field strength in it varies with time as E = at, where a is a positive constant. Find the angle of deviation of the proton as it comes out of the capacitor. (Assume that it does not collide with any of the plates.)

An electron accelerated by a potential difference V= 3 volt first enters into a uniform electric field of a parallel plate capacitor whose plates extend over a length l= 6 cm in the direction of initial velocity. The electric field is normal to the direction of initial velocity and its strength varies with time as E= alpha t, where alpha= 3600 V m^-1 s^-1. Then the electron enters into a uniform magnetic field of induction B = pi xx 10^-9 T. Direction of magnetic field is same as that of the electric field. Calculate pitch of helical path traced by the electron in the magnetic field. (Mass of electron, m = 9 xx 10^-31 kg )

The electric field (vec( E)) between two parallel plates of a capacitor will be uniform if.

Two plates are 1 cm aprt and the potential difference between them is 10 V. the electric field between the plates is

Two plates are 2 cm apart. If a potential difference of 10 V is applied between them. The electric field between the plates will be
