A beaker containing liquid is placed on a table, underneath a microscope with can be moved along a vertical scale. The microscope is focused, through the liquid into a mark on the table when the reading on the scale is a. it is next focused on the upper surface of the liquid and the reading is b. More liquid is added and the observations are repeated. The corresponding readings are c and d. The refractive index of the liquid is

Two blocks of masses m and M are connected by an inextensible light string as shown in the figure. When a constant horizontal force F acts on the block of the mass M, then tension in the string is : (Assume that constact between the ground and the two blocks are frictionless) and blocks will not topple. (Given: m=1kg,M=4kg,F=10N,θ=60∘)
