Question

A proton is about 1840 times heavier than an electron. When it is accelerated by a potential difference of 1 kV, its kinetic energy will be (A) 1840 keV (B) 1 / 1840 keV (C) 1 keV (D) 920 keV

Tardigrade Admin · Accepted Answer

Kinetic energy of proton, K=e Δ V=e × 103 V =1 keV

Q. A proton is about $1840$ times heavier than an electron. When it is accelerated by a potential difference of $1 kV$ , its kinetic energy will be

1840 keV

1 / 1840 keV

1 keV

920 keV

Kinetic energy of proton,
$K = e Δ V = e \times 1 0^{3} V = 1 k e V$
