a) As the separation increases, the forces of mutual attraction decrease. Provide a theory explaining why the for decrease. Refer to the fields rather than the Coulomb law to provide the view. Force on q, by 4, - 060 503 N b) Suppose that the sphere q, is released when the distance between the centers of the objects is 50 cm. Find a expression to calculate the instantaneous acceleration of q,. Hint: construct Newton's law showing Fnet actin on q2. You can ignore gravitational effects
