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 $
