Step 1: Understanding the Indian Space Missions.
Aditya-L1 is the mission launched by ISRO to study the Sun, and it completed its halo orbit around the Sun-Earth L1 point.
Step 2: Analyzing the options.
- (A) Gaganyaan L1: Gaganyaan is India's crewed mission, not related to the Sun-Earth L1 point.
- (B) Aditya-L1: This is the correct answer, as it is the mission designed to study the Sun and completed its halo orbit around the Sun-Earth L1 point.
- (C) Mangalyaan-L1: Mangalyaan is India's Mars mission and does not involve the Sun-Earth L1 point.
- (D) Chandrayaan-L1: Chandrayaan is ISRO's Moon mission, unrelated to the Sun-Earth L1 point.
Step 3: Conclusion.
The correct answer is (B) Aditya-L1, as it completed its orbit around the Sun-Earth L1 point.
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:
