PLEASE HELP ME SOON Four forces are exerted on each of the two objects shown below:

Which object will move in the up direction?

Object A but not Object B
Object B but not Object A
Both Object A and Object B
Neither Object A nor Object B

Electric charge is uniformly distributed inside a nonconducting sphere of radius 0.30 m. the electric field at a point p, which is 0.50 m from the center of the sphere, is 15,000 n/c and is directed radially outward. what is the maximum magnitude of the electric field due to this sphere

The force will determine the acceleration.

If anyone who can me with this hw? i would really appreciate it
