(a) A physics lab instructor is working on a new demonstration. She attaches two identical copper globes with mass m = 0.180 g to filaments of lengthL as shown in the figure.LiBoth globes have the same charge of 6.80 nC, and are in static equilibrium when 0 = 4.80°. What is L (in m)? Assume the filaments are massless.xDraw a free-body diagram, apply Newton's second law for a particle in equilibrium to one of the globes. Find an equation for the distance betweenthe two globes in terms of L and 0, and use this expression in your Coulomb force equation. m(b) What If? The charge on both globes is increased until each filament makes an angle of 0 = 9.60° with the vertical. If both globes have the sameelectric charge, what is the charge (in nC) on each globe in this case?XUse the same reasoning as in part (a), only now, use the length found in part (a) and the new angle to solve for the charge. nC

Two equally charged, 1.00 g spheres are placed with 4.00 cm between their centers. 2 When released, each begins to accelerate at 225 m/s . As the spheres move, do you expect the force between them to increase, decrease or remain the same? Use an equation to justify your reasoning. Calculate the spacing needed between the spheres that would cut the force between them in half.
