A solid sphere of mass m=2kg and specific gravity s=0.5 is held stationary relative to a tank filled with water. The tank is accelerating upward with acceleration 2m/s2. Calculate (a) Tension in the thread connected between the sphere and the bottom of the tank. (b) If the thread snaps, calculate the acceleration of sphere with respect to the tank. (Density of water =1000kgm−3,g=10ms−2).
