An electron moves with a velocity vec(v) in are electric field vec(E) if the angle between vec(V) and Vec(E) is neither 0 nor pi ,then path followed by the electron is

The electric flux is negative, if the angle between vec(dA) and vec (E)

If angle between vec a and vec b is pi/3 then angle between vec a and -2vec b is:

Torque on a dipole in a uniform electric field is maximum when the angle between vecp and vec E is _______

Torque acting on a dipole placed in electric field is minimum when angle between vecp and vec(E) is:

An electron is launched with velocity vec v in a uniform magnetic field vec B. The angle theta between vec v and vec B lies between 0 and pi /2 . Its velocity vector vec v returns to its initial value in a time interval of

An electron is launched with velocity vec v in a uniform magnetic field vec B. The angle theta between vec v and vec B lies between 0 and pi /2 . Its velocity vector vec v returns to its initial value in a time interval of

If vec a,vec b,vec c are three vectors such that vec a=vec b+vec c and the angle between vec b and vec c is pi/2, then
