It sounds like a special relativity question but I need more info for a total answer. But remember it's length in the lab frame is
L•sqrt(1-(v/c)^2) where L is the rest length, v is its velocity magnitude and c is the speed of light. Sqrt is the square root (I'm on a phone so I can't see the math equation editor)
The distance between the two balls at the given force is 0.7 m.
The given parameters;
- <em>mass of each ball, m = 0.8 kg</em>
- <em>gravitational force between the balls from sample problem C, F = 8.92 x 10⁻¹¹ N</em>
The distance between the balls is calculated by applying Coulomb's law as shown below;
Thus, the distance between the two balls is 0.7 m.

None of the choices is correct.
Power = work/time
or
energy/time
or
(force) x (speed).
