Q.1 Is mass of body affected on charging ? 

Q.2 Is electrostatic potential necessarily zero where electric field strength is Zero ? Explain your answer. 

Q.3 Are the paths of electrons straight line between successive collision (with the positive ions of the metals) in the (i) absence of electric field (ii) presence of electric field ? 

Q.4 Calculate the amount of charge flown in 2 seconds through a wire in which avariable current I=2t is flowing in the wire. The current is measured in ampere.

Q.5 How will the magnetic field intensity at the centre of a circular coil carrying current change, if the current through the coil is doubled and the radius through the coil is doubled and the radius of the coil is halved ? 

Q.6 What is the effect on a vertical spring carring a weight when a current is passedthrough a spring ? 

Q.7 A magnetic dipole is situated in the direction of magnetic field. What is its potential energy ? If it is rotated by 180º then what is the amount of work done? 

Q.8 What is the net magnetic moment of an atom of a diamagnetic material ? 

Q.9 Give four properties of electric field lines. 

Q.10 Define a dipole. Find torque for a dipole in a uniform external field. 

Q.11 Explain :

(i) Inside a conductor, electrostatic field is zero.

(ii) Electrostatic shielding. 

Q.12 Two charge -q and +q are located at a point A (0,0,-a) and B (0,0,+a) respectively. How much work is done in moving a test charge from point P (7,0,0) to Q (-3,0,0)?
