Two 4.0kg masses are 2.0m apart on a frictionless table. Each has 1.0uC of charge.
A.) What is the magnitude of the electric force on one of the masses? - I got 0.00225N and I need it in two significant figures so I typed in 2.3x10^-3 and 0.23x10^-2 and they are very close but I have to check my rounding still. Idk what to put!
B.) What is the initial acceleration of each mass if they are released and allowed to move?
