Step 1: Understanding the Quit India Movement.
The Quit India Movement was launched by Mahatma Gandhi in 1942 after the failure of the Cripps Mission. This mission was an attempt by the British to secure Indian support during World War II, but it was rejected by Indian leaders, leading to Gandhi's call for immediate independence.
Step 2: Analyzing the options.
- (A) Round Table Conference-III: This was a series of meetings between the British government and Indian leaders but did not directly lead to the Quit India Movement.
- (B) Cripps Mission: This is the correct answer. The failure of the Cripps Mission in 1942 prompted Gandhi to launch the Quit India Movement.
- (C) Cabinet Mission: The Cabinet Mission was another British effort, but it occurred after the Quit India Movement.
- (D) Salt March: The Salt March occurred earlier, in 1930, and was a key event in the Civil Disobedience Movement, not the Quit India Movement.
Step 3: Conclusion.
The correct answer is (B) Cripps Mission, as the failure of this mission directly led to the launch of the Quit India Movement.
A weight of $500\,$N is held on a smooth plane inclined at $30^\circ$ to the horizontal by a force $P$ acting at $30^\circ$ to the inclined plane as shown. Then the value of force $P$ is:
A steel wire of $20$ mm diameter is bent into a circular shape of $10$ m radius. If modulus of elasticity of wire is $2\times10^{5}\ \text{N/mm}^2$, then the maximum bending stress induced in wire is:
