The magnitude of a force, F, between two particles of masses m1 and m2 a distance r apart, varies with m1, m2, and r according to the formula F = C m1 m2 r, where C is a constant. The dimensions of force are [F] = M L/T2, where M stands for mass, L for length, and T for time. What are the dimensions of the constant C?

i cant see the choices man

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
