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.
