A point charge of +Q= 6.3 μC is placed at the center of an equilateral triangle. Two additional charges of +Q are placed at two of the triangles vertices such that the radius from each of the charges to the center is 0.19m. What is the magnitude of the net electrostatic force acting on the charge in the center of the triangle?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
