In the figure, two spheres of mass \( m=2.46 \mathrm{~kg} \). and a third sphere of mass \( M \) form an equilateral triangle, and a fourth sphere of mass \( \mathrm{m}_{4} \) is at the center of the triangle. The net gravitational force on that central sphere from the three other spheres is zero. (a) What is the value of mass \( M \) ? (b) If we double the value of \( m_{4} \). what then is the magnitude of the net gravitational force on the central sphere? (a) Number Units (b) Number Units
