Electrostatics Question 295

Question: An electron and a proton are at a distance of $ 1{AA} $ . The moment of this dipole will be (Cx m) [CPMT 1984]

Options:

A) $ 1.6\times 10^{19} $

B) $ 1.6\times {{10}^{-29}} $

C) $ 3.2\times 10^{19} $

D) $ 3.2\times 10^{29} $

Show Answer

Answer:

Correct Answer: B

Solution:

$ p=q\times ( \text{2}l )=\text{ 1}.\text{6}\times \text{1}{{0}^{\text{19}}}\times \text{1}{{0}^{\text{1}0}}=\text{ 1}.\text{6}\times \text{1}{{0}^{\text{29}}}C-m $
