A small sphere is charged to a potential of $50\mathrm{V}$ and a big hollow sphere is charged to potential of $100\mathrm{V}$. Charge will flow from the smaller sphere to the bigger one when
Show Hint
- the smaller one is placed inside the bigger one and connected by a wire
- the bigger one is placed inside the smaller one and connected by means of a wire
- bigger one placed by the side of the smaller one and connected by a wire
- smaller one placed by the side of the bigger one
The Correct Option is A
Solution and Explanation
Charge flows from higher potential to lower potential.
Step 2: Detailed Explanation:
When the smaller sphere is placed inside the bigger hollow sphere and connected, the potential of the inner sphere becomes higher due to induction.
Step 3: Final Answer:
Charge flows when the smaller one is placed inside the bigger one and connected.

Helicopters are very different from airplanes. They can do three things that airplanes cannot do. First, when airplanes move upward, they must also move forward, but helicopters can move straight up without moving ahead. Second, helicopters can fly backward, which airplanes cannot do. Third, helicopters can use their rotors to hover in the air, which is impossible for airplanes. Helicopters can perform actions that airplanes cannot, they are used for different tasks. Since, helicopters can take off without moving forward, they do not need a runway for take off. They are used in congested areas where there is no room for airplanes or in isolated areas, which do not have airports. Because they can hover, they are used on firefighting missions to drop water on fires. They are used in logging operations to lift trees out of forests. Helicopters are used as air ambulances to airlift patients out of situations, which are difficult to reach by conventional ambulances. The police used helicopters to follow suspects on the ground or to search for cars on the ground. Of course, helicopters have military uses because of their design and capabilities.
