Question

The electric dipole moment of an electron
and a proton 4.3nm apart, is

Answer 1

$\underline{ \huge \boxed{ \bold{ \mathfrak{ \purple{Answer}}}}}$

Given :

Distance between electron and proton is 4.3 nm.

To Find :

electric dipole moment.

Formula :

Formula of electric dipole is given by...

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \dag \: \underline{ \boxed{ \bold{ \rm{ \pink{p = 2aq}}}}} \: \dag$

where 2a = distance between both particle and q = charge on particle

Calculation :

$\leadsto \rm \: p = 4.3 \times {10}^{ - 9} \times 1.6 \times {10}^{ - 19} \\ \\ \therefore \: \underline{ \boxed{ \bold{ \rm{ \orange{p = 6.88 \times {10}^{ - 28} \: C {m}^{2} }}}}} \: \red{ \clubsuit}$

Answer 2

$\huge \fcolorbox{red}{pink}{Solution :)}$

Given ,

Distance between electron and proton (2a) is 4.3 nano meter

In terms of SI unit ,

Distance between electron and proton (2a) is 4.3 × (10)^-9

We know that , the dipole moment (P) is the product of either charge (q) and dipole length (2a) , so

$\sf \large \fbox{Dipole \: moment = q \times 2a}$

Substitute the known values , we get

P = 1.6 × (10)^-19 × 4.3 × (10)^-9

P = 1.6 × 4.3 × (10)^-28

P = 16 × 43 × (10)^-30

P = 688 × (10)^-30 Coulomb meter

Hence , the required value of dipole moment is 688 × (10)^-30 Coulomb meter
