PHXII01:ELECTRIC CHARGES AND FIELDS

357968 A uniformly charged conducting sphere of 4.4 \(m\) diameter has a surface charge density of \(60\mu C{m^{ - 2}}\). The charge on the sphere is

1 \(7.3 \times {10^{ - 3}}C\)
2 \(3.7 \times {10^{ - 6}}C\)
3 \(7.3 \times {10^{ - 6}}C\)
4 \(3.7 \times {10^{ - 3}}C\)

357969 I.
If a system contains two charges \({q_1}\) and \({q_2}\) the total charge of the system is obtained simply by adding algebraically \({q_1}\) and \({q_2}\)
II.
Charge has magnitude but no direction, similar to mass
III.
Mass of a body is always positive whereas a charge can be either positive or negative
Which of the following statements is/are correct?

1 Only I
2 Only III
3 Only II
4 I, II and III
PHXII01:ELECTRIC CHARGES AND FIELDS

357970 Assertion :
Charge is quantized.
Reason :
Charge which is less than \(1\,C\) is not possible.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

357971 A body has \({-40 \mu C}\) micro coulomb of charge. Number of additional (excess) electrons in it will be

1 \({4 \times 10^{-5}}\)
2 \({8 \times 10^{-17}}\)
3 \({2 \cdot 5 \times 10^{14}}\)
4 \({4 \cdot 5 \times 10^{-17}}\)
