Question

Question 4 of 20 Metal sphere A has a charge of − Q . An identical metal sphere B has a charge of + 2 Q . The magnitude of the electric force on sphere B due to sphere A is F . The magnitude of the electric force on sphere A due to sphere B must be

Answer 1

The magnitude of the electric force on sphere A due to sphere B must be F

Step-by-step explanation:

Metal sphere A has a charge = −Q

Metal sphere B has a charge = 2Q

The magnitude of the electric force on sphere B due to sphere A = F

The magnitude of the electric force on sphere A due to sphere B would be same as magnitude of the electric force on sphere B due to sphere A that is F and this force will be attractive in nature due to opposite polarity of charges.
