If power of a point source of sound is 'P' at the center of a cylinder, the power through the curved portion of the cylinder is

a point charge q is placed at the centre of a cylinder of length L and radius R the electric flux through the curved surface of the cylinder is

A charge q is placed at the centre of a cylinder of radius R and length 2R. Then electric flux through the curved surface of the cylinder is

A uniform solid cylinder of mass m and radius R is placed on a rough horizontal surface. A horizontal constant force F is applied at the top point P of the cylinder so that it start pure rolling. The acceleration of the cylinder is

A sphere and the base of a cylinder have equal radii. The diameter of the sphere is equal to the height of the cylinder. The ratio of the curved surface are of the cylinder and surface area of the sphere is __________.

If the curved surface area of the cylinder is 440 cm^(2) and the height of the cylinder is 10 cm, then what is the radius (in cm) of the cylinder ?

A point charge 'q' is placed at the centre of left circular end of a cylinder of length l=4cm and radius R=3 cm shown. Then the electric flux through the curved surface of the cylinder is

A cylinder of radius R and length l is placed in a uniform electric field E parallel to the axis of the cylinder. The total flux over the curved surface of the cylinder is

Two uniform solid cylinders, each of mass m = 10 kg and radius r = 150 mm, are connected by a rough belt as shown. If the system is released from rest, determine the velocity of the centre of cylinder A after it has moved through 1.2 m & the tension in the portion of the belt connecting the two cylinders.

Intensity of a point source of sound is 0.2 W/m^(2) at a place. If the distance of source and power are doubled,the intensity at that place becomes to

As shown in the adjacent figure, a sphere is placed in a cylinder. It touches the top, bottom and the curved surface of the cylinder. If radius of the base of the cylinder is 'r', (i) what is ratio of the radii of the sphere and the cylinder? (ii)what is the ratio of the curved surface area of the cylinder and the surface area of the sphere? (iii) what is the ratio of the volumes of the cylinder and the sphere?
