An electron and a proton are at a distance of 1A˚1Å. The moment of this dipole will be (C × m)

A

1.6×10191.6 \times 10^{19}

B

1.6×10−291.6 \times 10^{- 29}

C

3.2×10193.2 \times 10^{19}

D

3.2×10293.2 \times 10^{29}

Answer

1.6×10−291.6 \times 10^{- 29}

Explanation

Solution

p = q × (2l) = 1.6 × 10–19 × 10–10 = 1.6 × 10–29 C-m
