Question

Two parallel plates separated by 'd' mm are kept at potential difference of 'V' volt. A particle of mass 'm' and charge 'q' enters in it with some velocity. The acceleration of the particle will be ______.

विकल्प

• `(qV)/(dm)`

• `(qd)/(Vm)`

• `(qm)/(Vd)`

• `q/(dmV)`

Answer 1

Two parallel plates separated by 'd' mm are kept at potential difference of 'V' volt. A particle of mass 'm' and charge 'q' enters in it with some velocity. The acceleration of the particle will be `underline((qV)/(dm))`.

Explanation:

Electric field between the plates `E=V/d`

Force on charge q : F = qE = `(qV)/d`

Acceleration a : `a=F/m=(qV)/(dm)`
