How much work is required to be done to separate the charges of a dipole till infinity with Q ± 7μC and r = 0.18 m?

Expert Answer:

Given:

Q  = ± 7μC

r = 0.18 m

Energy to be stored in the dipole, U = -K Syntax error from line 1 column 49 to line 1 column 73. Unexpected 'mathsize'.

U = - Syntax error from line 1 column 49 to line 1 column 73. Unexpected 'mathsize'.

= - 2.455 J

Therefor, 2.455 J work has to be done to separate the charges till infinity. The negative sign indicates that the work has to be done against the attraction of charges.
