| Directions (Q. Nos. 26): For the following questions. Choose the correct answers from the codes [a], [b], [c] and [d] defined as follows. |
| Statement I Charge is invariant in nature i.e., in different inertial frames charge on an object is same. |
| Statement II A gas consisting of hydrogen molecules is neutral in nature. |
A) Statement I is true. Statement II is also true and Statement II is the correct explanation of Statement I.
B) Statement I is true. Statement II is also true and Statement II is not the correct explanation of Statement I.
C) Statement I is true. Statement II is false.
D) Statement I is false. Statement II is true.
Correct Answer: B
Solution :
Charges are always conversed for an isolated system. Electrons in hydrogen molecules move at much higher velocities than protons. Therefore, if the charge depends on the velocity, the charges of the electrons and protons would not compensate each other and the gas would be charged. However, no charge has been observed in hydrogen gas upto a very good accuracy.
