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?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
