Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.116 n when their center-to-center separation is 65.4 cm. the spheres are then connected by a thin conducting wire. when the wire is removed, the spheres repel each other with an electrostatic force of 0.0273 n. of the initial charges on the spheres, with a positive net charge, what was (a) the negative charge on one of them and (b) the positive charge on the other? (assume the negative charge has smaller magnitude.)

Part a)

Part b)

Explanation:

Let the charge on two spheres is q1 and q2

now the force between two charges are

now when we connect then with conducting wire then both sphere will equally divide the charge

so we will have

now we have

now we will have

Now we can solve above two equations

Part a)

negative charge on the sphere is

Part b)

positive charge on the sphere is

explanation:

the masses of the objects and the distance between them

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
