Q)

A bottle has an opening of radius a and length b. A cork of length b and radius (a+Δa) where is (Δ<<a) is compressed to fit into the opening completely (See figure). If the bulk modulus of cork is B and frictional coefficient between the bottle and cork is μ then the force needed to push the cork into the bottle is :

(1)(πμBb)Δa(2)(2πμBb)Δa(3)(πμBb)a(4)(4πμBb)Δa
