JEE Main - Maths
There are (4n + 1) terms in a certain sequence of which the first (2n + 1) terms form an A.P. of common difference 2 and the last (2n + 1) terms are in G.P. of common ratio 1/2 If the middle term of both A.P. and G.P. are the same, then find the mid-term of this sequence.

JEE Main - Physics
A wooden block weighing 80 N rests on a rough horizontal plane, the coefficient of friction between the two being µ=0.4. If a bullet weighing 0.4 N is fired horizontally in to the block with muzzle velocity v= 500 m/s, how far will the block be displaced from its initial position? Assume that the bullet remains inside the block.
