Question

A proton mass M and alpha particle mass 4M are in a uniform electric field the the ratio of their acceleration is ??

Answer 1

Explanation:

F = qE

here E is constant

For proton

Ma = qE

a1 = 1×E/M

For alplha particle

4Ma = 2×E

a2 = E/2M

$\frac{a1}{a2} = \frac{e}{m} \times \frac{2m}{e} = 2$
