Each of the six ideal batteries of emf 20 V is connected to an external resistance of 4 Ω as shown in the figure. The current through the resistance is
A billiard ball of mass M, moving with velocity v1 collides with another ball of the same mass but at rest. If the collision is elastic, the angle of divergence after the collision is
In the given circuit, a charge of + 80 μC is given to upper plate of a 4 μF capacitor. At steady state, the charge on the upper plate of the 3 μF capacitor is
A force F is applied on a square plate of length L. If the percentage error in the determination of L is 3% and in F is 4%, then permissible error in the calculation of pressure is
A ball is thrown at a speed of 20 m/s at an angle of 30° with the horizontal. The maximum height reached by the ball is
