Expert Answer

Step 1

When a charged conducting body is allowed to be in contact with another neutral conducting body, Charge will flow the first one to the second one till the potential of two spheres become equal. Here, both spheres are identical. So, the charge flow will stop till both the spheres have same magnitude of charges.

Step 2

When it is separated thereafter, the object which loose electrons become positively charged and the one which gain charges became negatively charged. Thus, option (d) is correct.

Step 3

Option (a) can be correct only when the spheres are brought closer to each other. When it touches, each other, situation changes. Thus, option (a) is incorrect.

Like charges will tries to at minimum distance and unlike charges would tries to align at maximum distance. Thus, optio...
