Question 1

A uniform magnetic field of induction B is confined to a cylindrical region of radius R. The magnetic field is increasing at a constant rate of  (tesla/second). An electron of charge q, placed at the point P on the periphery of the field experiences an acceleration

Question 2

A triangular wire frame (each side = 2m) is placed in a region of time variant magnetic field having . The magnetic field is perpendicular to the plane of the triangle. The base of the triangle AB has a resistance 1Ω while the other two sides have resistance 2 Ω each. The magnitude of potential difference between the points A and B will be

Question 3

A constant voltage is applied between the two ends of a uniform metallic wire. Some heat is developed in it. The heat developed is doubled if

Question 4

When electric bulbs of same power, but different marked voltage are connected in series across the power line, their brightness will be

Question 5

A wire when connected to 220 V mains supply has power dissipation P1. Now the wire is cut into two equal pieces which are connected in parallel to the same supply. Power dissipation in this case is P2. Then P2 : P1 is :

Question 6

Two bulbs rated (25 W – 220 V) and (100 W – 220V) are connected in series to a 440 V line. Which one is likely to fuse ?

Question 7

A storage battery is connected to a charger for charging with a voltage of 12.5 Volts. The internal resistance of the storage battery is 1 Ω. When the charging current is 0.5 A, the emf of the storage battery is:
