Magnetic Spheres

Magnetic Spheres
physics question (electric and magnetic fields)?

two isolated spheres, a and b are 2 m apart. sphere A has a charge q and sphere B has a charge 2q. electrostatic force on sphare A is ?
The same as spheree B
two times that on sphere B
half that on sphere B
four times that on sphere B
or not enough info given?

Right, we don’t need any equations for this problem, just a little bit of logical thinking!

The force that acts between the two spheres is directly proportional the the sizes of each charge. because the charge on sphere b is twice as strong as the charge on sphere a, the force that acts on sphere a must be twice as strong as the force that acts upon sphere b.

Hope that helps!
