Electrostatics Question 445
Question: If $ 4\times 10^{20}eV $ energy is required to move a charge of 0.25 coulomb between two points. Then what will be the potential difference between them [MHCET 2002]
Options:
A) 178 V
B) 256 V
C) 356 V
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
By using, $ KE=QV\Rightarrow 4\times 10^{20}\times 1.6\times 10^{19} $
$ =0.25\times V\Rightarrow V=256volt $
