Q. A gas expands isothermally at 300 K from a volume of 1 m³ to 2 m³. If the pressure at the initial state is 100 kPa, what is the work done by the gas?
Q. A gas is compressed isothermally from a volume of 4 L to 1 L at a constant temperature of 300 K. If the initial pressure is 1 atm, what is the final pressure?
A.
4 atm
B.
3 atm
C.
2 atm
D.
1 atm
Solution
Using Boyle's Law, P1V1 = P2V2, we find P2 = P1 * (V1/V2) = 1 atm * (4 L / 1 L) = 4 atm.
Q. A loop of wire is moved into a magnetic field at a constant speed. What happens to the induced current as the loop enters the magnetic field? (2023)
A.
It increases
B.
It decreases
C.
It remains constant
D.
It becomes zero
Solution
As the loop enters the magnetic field, the change in magnetic flux increases, leading to an increase in the induced current.
Q. A loop of wire is placed in a uniform magnetic field. If the magnetic field is increased uniformly, what happens to the induced current in the loop?
A.
It increases
B.
It decreases
C.
It remains constant
D.
It becomes zero
Solution
According to Faraday's law, an increase in magnetic field through the loop induces a current in the loop, which increases as the rate of change of magnetic flux increases.
Q. A loop of wire is rotated in a uniform magnetic field. What is the effect on the induced current? (2019)
A.
It remains constant
B.
It reverses direction
C.
It increases
D.
It decreases
Solution
As the loop rotates, the angle between the magnetic field and the normal to the loop changes, which causes the direction of the induced current to reverse periodically.
Q. A magnetic field is directed into the plane of the paper. If a positive charge moves to the right, what is the direction of the magnetic force acting on it? (2021)
A.
Upwards
B.
Downwards
C.
To the left
D.
To the right
Solution
Using the right-hand rule, if the magnetic field is into the paper and the charge moves to the right, the force will be upwards.
