Electrostatics Question 466

Question: A particle has a mass 400 times than that of the electron and charge is double than that of a electron. It is accelerated by 5V of potential difference. Initially the particle was at rest, then its final kinetic energy will be [MP PMT 1990; DPMT 1999]

Options:

A) 5 eV

B) 10 eV

C) 100 eV

D) 2000 eV

Show Answer

Answer:

Correct Answer: B

Solution:

$ \Delta E=2e\times 5V=10eV $

therefore Final kinetic energy $ =10eV $
