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 $
