Q. A charge of +5 μC is placed in an electric field of 1000 N/C. What is the work done in moving the charge 0.2 m in the direction of the field? (2022)
A.
1 J
B.
0.1 J
C.
0.5 J
D.
2 J
Solution
Work done W = F * d = (E * q) * d = (1000 N/C * 5 × 10^-6 C) * 0.2 m = 0.1 J.
Q. A flywheel is a device used to store rotational energy. If the moment of inertia of the flywheel is I and it rotates with an angular velocity ω, what is its rotational kinetic energy? (2020)
A.
(1/2)Iω^2
B.
(1/4)Iω^2
C.
(1/3)Iω^2
D.
(1/5)Iω^2
Solution
The rotational kinetic energy is given by K.E. = (1/2)Iω^2.
Q. A flywheel is rotating with an angular velocity of 10 rad/s. If the moment of inertia of the flywheel is 2 kg·m², what is its rotational kinetic energy? (2020)
A.
100 J
B.
50 J
C.
20 J
D.
10 J
Solution
Rotational kinetic energy K.E. = (1/2)Iω² = (1/2)(2)(10)² = 100 J.
