Deutron and $\alpha -$ particle are put $1^{\hat{A}}$ apart in air. Magnitude of intensity of electric field due to deutron at $\alpha -$ particle is

Zero

$2.88 \times 10^{11} \text{ newton/coulombr}$

$1.44 \times 10^{11} \text{ newton/coulomb}$

$5.76 \times 10^{11}$ newton/coulomb

Text Solution

Verified by Experts

The correct answer is:

Due to deutron, intensity of electric field at 1 Å distance,

$E = \frac{1}{4 \pi \epsilon_0} \cdot \frac{e}{r^2}$

$\frac{9 \times 10^{9} \times 1.6 \times 10^{-19}}{10^{-20}} = 1.44 \times 10^{11} \mathrm{~N} / \mathrm{C}.$
