Electrostatics Question 399
Question: A proton is accelerated through 50,000 V. Its energy will increase by [JIPMER 1999]
Options:
A) 5000 eV
B) $ 8\times {{10}^{-15}} $ J
C) 5000 J
D) 50,000 J
Show Answer
Answer:
Correct Answer: B
Solution:
Kinetic energy $ K=Q.V\Rightarrow K=( +e )( 50000V ) $
$ =50000eV=50000\times 1.6\times 10^{19}J=8\times 10^{15}J $
