Two particles of masses m₁, m₂ move with initial velociteis u₁ and u₂. On collision, one of the particles get excited to higher level, after abosrbing energy e. If final velocities of particles be v₁ and v₂ then we must have :

A rod of weight W is supported by two parallel knife edges A and B and is in equilibrium in a horizontal position. The knives are at a distance d from each other. The centre of mass of the rod is at distance x from A. The normal reaction on A is :-

A ship A is moving Westwards with a speed of 10 km h–1 and a ship B 100 km South of A, is moving Northwards with a speed of 10 km h–1. The time after which the distance between them becomes shortest, is :-

Which of the following is the most correct electron displacement for a nucleophilic reaction to take place?
