Question

An alpha particle is accelerated through a potential difference of 10 kv find the gain in kinetic energy

Answer 1

Given that,

An alpha particle is accelerated through a potential difference of 10 kV.

To find,

Gain in kinetic energy.

Solution,

We know that,

Charge on an electron is $1.6\times 10^{-19}\ C$. The gain is kinetic energy is equal to :

$E=qV\\\\E=eV\\\\E=1.6\times 10^{-19}\times 10^4\\\\E=1.6\times 10^{-15}\ J$

So, the gain in kinetic energy is $1.6\times 10^{-15}\ J$.
