Question

an electric dipole is formed by +2 uc and -2 uc charges at 1 mm distance. the magnitude of electric dipole moment of dipole is? ​

Answer 1

Answer:

Electric dipole moment = 2 x $10^{-9}$ C m

Explanation:

Dipole moment is given by : P = 2a x q

• P is dipole moment
• 2a is distance between the 2 charges
• q is the magnitude of the charges

q = 2μ C = 2 x $10^{-6}$ C

2a = 1 mm = 1 x $10^{-3}$ m

P = 1 x $10^{-3}$ x  2 x $10^{-6}$ = 2 x $10^{-9}$ C m

Answer 2

Answer: 2 x 10^-9

Distance = 1mm = 1 x 10^-3 m

Charge = 2 micro C = 2 x 10^-6 C

Dipole Moment = 2aq (Where 2a is distance b/w dipole and q is charge) = (1 x 10^-3) x (2 x 10^-6) = 2 x 10^-9 metre Coulomb
