Two plastic bowling balls, 1 and 2, are rubbed with cloth until they each carry a uniformly distributed charge of magnitude 0.60 nc . ball 1 is negatively charged, and ball 2 is positively charged. the balls are held apart by a 800-mm stick stuck through the holes so that it runs from the center of one ball to the center of the other. what is the magnitude of the dipole moment of the arrangement?

The electric dipole moment for a pair of opposite charges of magnitude q is defined as the magnitude of the charge times the distance between them and the defined direction is toward the positive charge, mathematically can be written as,

Here,

q= Chage

d= Distance

Our values are given as,

Replacing,

Therefore the magnitude of the dipole moment of the arrangement is

The magnitude of the dipole moment of the given arrangment of the balls is

Its magnitude can be defined as the product of the charge and distance between them.

Where,

- Chage  =  0.60 nC =

-  Distance = 800-mm  

Put the values in the formula,

Therefore, the magnitude of the dipole moment of the given arrangement of the balls is
