2. Two waves of same frequency have amplitudes 1.00 and 2.00. They interfere at a point where their phase difference is 60.0°. What is the resultant amplitude at that point?
3. On what factors does the period of oscillation of a bar magnet in a uniform magnetic field depend?
4. Write the units of (i) Charge, (ii) Electric field strength, (iii) Electric potential and (iv) Capacitance.
