1.	For distance far away from centre of dipole the change in magnitude of electric field with change in distance from the centre of dipole is ?
	zero.
	more in case of axis of dipole as compared to equatorial plane
	more in case of equatorial plane of dipole as compared to axis of dipole.
	same in equatorial plane as well as axis of dipole.
	Answer: more in case of axis of dipole as compared to equatorial plane Explanation: For distance far away from centre of dipole the change in magnitude of electric field with change in distance from the centre of dipole is. more in case of axis of dipole as compared to equatorial plane of dipole.

8.	The unit of electric field is not equivalent to ?
	J / C
	N / C
	J / Cm
	V / m
	Answer: J / C Explanation: By unit and dimension - electric field. N/C= volt/meter= J/c?mt Therefore, dimensions of E=MLT ?3A ?1 which is a vector quantity. So, the correct answer is B:J/C Because, it gives the answer work done per unit charge which is called Potential.
