Question

A proton and an `alpha`-particle are released in a uniform electric field. Find the ratio of (a) forces experienced by them (b) accelerations gained by each

Answer 1

(a) As `F= Eq, F prop q, implies F_(P)/F_(alpha)=Q_(P)/Q_(alpha)=1/2" ":. F_(P)/F_(alpha)=1/2`
(b) As `a=E_(Q)/m implies a prop Q/m implies a_(P)/a_(alpha)=Q_(P)/Q_(alpha)xxm_(alpha)/m_(P)=1/2 xx4/1=2/1" ":. a_(P)/a_(alpha)=2/1`
