Post by: sheilaspns on Oct 11, 2019

Question 1

The figure shows electric field lines arising from two small charged particles P and Q. Consider the following two statements:
(i)The charge on P is smaller than the charge on Q.
(ii)The electrostatic force on P is smaller than the force on Q.



Which of the above statements are true?
◦ Only (i) is true.
◦ Only (ii) is true.
◦ Both (i) and (ii) are true.
◦ Neither (i) nor (ii) is true.

Question 2

Two stationary point charges q1 and q2 are shown in the figure along with a sketch of some field lines representing the electric field produced by them. What can you deduce from the sketch?



q1 is positive and q2 is negative; the magnitude of q1 is greater than the magnitude of q2.
q1 is negative and q2 is positive; the magnitudes are equal.
q1 and q2 have the same sign; the magnitudes are equal.
q1 and q2 have the same sign; the magnitude of q1 is greater than the magnitude of q2.
q1 is negative and q2 is positive; the magnitude of q1 is less than the magnitude of q2.
