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 h1 and a ship B 100 km South of A, is moving Northwards with a speed of 10 km h1. The time after which the distance between them becomes shortest, is :-
