Q5. Fundamental forces in nature are those
Answer : Option A
Explaination / Solution:
The universe has a lot of forces, a lot of pushes and pulls. We're always pushing or pulling something, even if only the ground. But it turns out that in physics, there are really only four fundamental forces from which everything else is derived: the strong force, the weak force, the electromagnetic force, and the gravitational force.
Q6. An electrolytic capacitor is marked 8 μF, 220 V. It can be used in a circuit where the p.d. across the capacitor may be
Answer : Option D
Explaination / Solution:
The break down potential of the capacitor is 220 V. In order to prevent damage to a capacitor, it should be always used in a circuit where the p.d is less than its break down potential. The p.d difference can only be 200 V.

Q9. A fly wheel rotating about a fixed axis has a kinetic energy of 360 joule when its angular speed is 30 radians per second. The moment of inertia of the fly wheel about the axis of rotation is
Answer : Option B
Explaination / Solution:
K=12Iω2K=360Jω=30rad/sI=2Kω2=2×36030×30=0.8Kgm2
Q10. When a soap bubble is charged, it
Answer : Option B
Explaination / Solution:
Charge will be distributed uniformly on the surface of a bubble if the bubble is charged.The bubble will expand because the charged particles uniformly distributed on it cause them to repel each other due to the electrostatic force. This will happen to both positive and negatively charged bubbles because of the charge on it.
