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∘)

A thin biconvex lens of refractive index 3/2 is placed on a horizontal plane mirror as shown. The space between the lens and the mirror is then filled with water of refractive index 4/3. It is found that when a point object is placed 15cm above the lens on its principal axis, the object coincides with its own images. On representing with another liquid, the object and the image again coincide at a distance 25cm from the lens

An a.c. source of angular frequency omega is fed across a resistor R and a capacitor C in series. The current registered is I. If you the frequency of source is changed to omega//3, maintaining the same voltage, current in the circuits is found to be halved. Caculate the ratio of reactance to resistance at the original frequency omega.
