A wooden stick 2 m long is floating on the surface of water. The surface tension of water 0.07 N/m. By putting soap solution on one side of the sticks the surface tension is reduced to 0.06 N/m. The net force on the stick will be

MCQs-PYQs-12th-jee

Force necessary to pull a circular plate of 5 cm radius from water surface for which surface tension is 75 dynes/cm, is

MCQs-PYQs-12th-jee

A beaker of radius 15 cm is filled with a liquid of surface tension 0.075 N/m. Force across an imaginary diameter on the surface of the liquid is

The following bodies are made to roll up (without slipping) the same inclined plane from a horizontal plane : (i) a ring of radius R, (ii) a solid cylinder of radius R/2 and (iii) a solid sphere of radius R/4. If in each case, the speed of the centre of mass at the bottom of the incline is same, the ratio of the maximum height they climb is :

MCQs-PYQs-12th-jee

A solid sphere and solid cylinder of identical radii approach an incline with the same linear velocity (see figure). Both roll without slipping all throughout. The two climb maximum heights h_sph and h_cyl on the incline. The ratio h_sph /h_cyl is given by :

Let the moment of inertia of a hollow cylinder of length 30 cm (inner radius 10 cm and outer radius 20 cm ) , about its axis be I . The radius of a thin cylinder of the same mass such that its moment of inertia about its axis is also I, is:

MCQs-PYQs-12th-jee

A circular disc D1 of mass M and radius R has two identical discsD2 and D3 of the same mass M and radius R attached rigidly at its opposite ends.The moment of inertia of the system about the axis OO’ passing through the centre ofD1,as shown in the figure will be

MCQs-PYQs-12th-jee

A slab is subjected to two forces F1 and F2 of same magnitude F as shown in the figure. Force F2 is in x-y plane while force F1 acts along z-axis at the point (2 î+3 ĵ). The moment of these forces about point O will be

MCQs-PYQs-12th-jee

A rigid massless rod of length 31 has two masses attached at each end as shown in the figure. The rod is pivoted at a point on the horizontal axis (see figure) when released from initial horizontal position, its instantaneous angular acceleration will be
