A body of mass m is attached to the lower end of a spring whose upper end is fixed. The spring has negligible mass. When the mass m is slightly pulled down and released, it oscillates with a time period of 3s. When the mass mis increased by 1 kg, the time period of oscillations becomes 5 s. The value of m in kg is

When two displacement represented by y1 = a sin(ωt) and y2 = b cos(ωt) are superimposed the motion is

The magnetic field in a certain region of space is given by B=8.35×10^−2i T. A proton is shot into the field with velocity v=(2×10^5i + 4×10^5j)m/s. The proton follows a helical path in the field. The distance moved by proton in the x-direction during the period of one revolution in the yz-plane will be ( mass of proton=1.67×10^−27kg)

Two batteries of e.m.f. 4 V and 8 V with internal resistances 1Ω and 2Ω are connected in a circuit with a resistance of 9Ω as shown in figure. The current and potential difference between the points P and Q are

A battery of emf 8 V with internal resistance 0.5Ω is being charged by a 120 V d.c. supply using a series resistance of 15.5Ω. The terminal voltage of the battery is

In the circuit given here, the points A, B and C are 70 V, zero, 10 V respectively. Then

The figure here shows a portion of a circuit. What are the magnitude and direction of the current i in the lower right-handwire

The figure shows a network of currents. The magnitude of currents is shown here. The current I will be

The Current in the arm CD of the circuit will be

A current of 6A enters one corner P of an equilateral triangle PQR having 3 wires of resistances 2Ω each and leaves by the corner R. Then the current I1, and 12 are
