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 $
