Two equal and opposite charges of masses `m_(1)` and `m_(2)` are accelerated in an uniform electric field through the same distance. What is the ratio of their accelerations if their ratio of mass is `(m_(1))/(m_(2))= 0.5` ?

Options

A. `(a_(1))/(a_(2))=2`
B. `(a_(1))/(a_(2))=0.5`
C. `(a_(1))/(a_(2))=3`
D. `(a_(1))/(a_(2))=1`

Answer

A

Explanation

Force is same in magnitude for both.
`:.m_(1)a_(1)=m_(2)a_(2)`
`(a_(1))/(a_(2))=(m_(2))/(m_(1))=(1)/(0.5)=2`
