To solve this problem we will use the concept of electric field, with which we will make the proportional comparison as we move away from the center. So we have the maximum electric field is given as,
Where,
Q = Charge
R = Radius
Electric field inside the sphere is given as,
Electric field outside the sphere is given as,
Therefore the possible values are 3.5cm and 9.9cm: The correct answer is D.
The net force is zero due to the direction.
We need to know about force resultant to solve this problem. The force resultant is the total net force applied to the object according to the direction. It can be written as
R = F1 + F2 + ... + Fn
where R is force resultant (net force)
From the question above, we know that
F1 = F2 = F N
Because the direction is the same, the force will be minus each other.
R = F1 - F2
R = F - F
R = 0 N
Hence, the net force is 0 N

The answer is answer chioce B.
I'm not sure which two rocks you're talking about.
If the volumes of the two rocks are equal, then the rock with the greater density has more mass than the rock with the smaller density, and it also weighs more.
