Question

an alpha particle is kept in an electric field of 15×10^4 nc^-1. calculate the force on the particle.

Answer 1

Hope it will help u. . . . ^_^

Answer 2

Answer:

Force on the particle, $4.8\times 10^{-14}\ N$

Explanation:

It is given that,

Electric field, $E=15\times 10^4\ N/C$

Charge on alpha particle, $q=2e=3.2\times 10^{-19}\ C$

We have to find the force on the particle. Electric force act on it. It is given by :

F = q E

$F=3.2\times 10^{-19}\ C\times 15\times 10^4\ N/C$

$F=4.8\times 10^{-14}\ N$

Hence, the electric force on the particle is $4.8\times 10^{-14}\ N$
