Three masses A, B & C revolve in the same plane about a centre O in the plane. The radii of A, B & C are respectively 36cm, 50cm, and 30cm. Angle AOB = 90° and angle BOC
120°. The weight of C 25 KN. Determine the weight of A & B in order that the three masses
may balance.

not too sure thinking all accelerations are pointed down

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
