A bob of mass m is tied with a thread and is made to move in a circular path on a horizontal frictionless table about point O as shown in the figure. A hypothetical electric field exists in the radial direction along the surface of the table. In this condition, the bob is uncharged and the tension in the threads is T. If now the bob is given some charge, then
Tension in thread must increase
Tension in thread may increase or decrease
Tension in thread must decrease
Tension in thread will remain unchanged

Consider the situation show in the figure. The wall is smooth but the surfaces of blocks A and B in contact are rough. The friction on A due to B in equilibrium
Is zero
The system cannot remain in equilibrium for any value of F
Is upward
Is downward

An engine is attached to a wagon through a shock absorber of length 1.5m. The entire system with a total mass of 5000 kg was moving with a speed of 36 1 kmh , when the brakes are applied to bring it to rest. In this process, the spring of the shock absorber gets compressed by 1.0m, if 90% of the energy of the wagon is lost due to friction, the spring constant is
