Two charged balls are connected by an in extensible thread of length 3m. Masses of balls are 2kg and 1kg, the charges are +20micocoulomb and - 100microcoulomb. What minimum constant external force F must be applied to the ball of mass 1 kg so that the thread does not slack? Neglect friction and gravity.

Two masses, m1=3 kg and m2=2 kg are on a horizontal surface and are connected together via a massless rope. An external force F pulls on m1 at an angle q=30° from the horizontal, as shown in the Figure 2 below. There is friction between m2 and the surface, with coefficients of friction ms=0.4 and mk=0.3, however the friction between m1 and the surface is negligibly small. What is the minimum value of F such that the masses will begin...
