1. A car battery is of 12V. Eight dry cells of 1.5V in series also give 12V, but such a combination is not used to start a car. Why?

2. A beam of α particle projected along the positive X axis experiences a force due to magnetic field along the positive Y axis. What is the direction of magnetic field?

3. Will there be any current induced in the coil shown in the figure if the bar magnet is swiftly moved towards the coil? Justify your answer.

4. Where on earth’s surface is the horizontal component of earth’s magnetic field zero?

5. Write two characteristics of stable equilibrium condition of an electric dipole placed in a uniform electric field.

6. You are given two constantan wires P and Q of length area of cross-section (L, A) and (2L, A/2) respectively. When two wires are connected in series, effective resistance is R_s and R_p when connected in parallel. Calculate R_s/R_p.

(OR)

An external resistance 'R' is connected across a source of emf 'E' and internal resistance 'r'. Write the relation between terminal voltage and 'R'. Sketch a graph of terminal voltage versus 'R'. Justify the shape of the graph.

7. The magnitudes of velocities of an alpha particle and proton entering in a magnetic field are in the ratio of 6:1. On entering the field, they move on the circular paths.
