A uniform plate with a circular hole lies over a smooth horizontal surface. C is the center of the plate and X is at the edge of the plate,as shown.Now,if the temperature of the plate is increased

A square metal plate with a hole is at temperature theta is present on smooth horizontal surface. Point P & C are marked on the plate, where C is centre of mass of the plate with the hole shown. When temperature of the plate is increased then the point.

From a uniform circular plate of radius R, a small circular plate of radius R/4 is cut off as shown. If O is the center of the complete plate, then the x coordinate of the new center of mass of the remaining plate will be: X o Y

A uniform rectangular plate of mass m which is free to rotate about the smooth vwerticle hinge passing through the centre and perpendicular to the plate, is lying on a smooth horizontal surface. A particle of mass m is moving with speed 'u' collides with the plate and sticks to it as shown in figure. The angular velocity of the platye after colli9sion will be

A circular metal plate of radius 10 cm is given a charge of 20muC on its surface. The charge density of the plate is

The coefficient of linear expansion of aluminium is 23xx10^(-6)//""^@C . A circular hole in an aluminium plate 2.725 is cm in diameter at 0^@C .What is the diameter of the hole if the temperature of the plate is raised to 100^@C ?

A uniform circular plate of radius 2R has a circular hole of radius R cut out of it. The centre of the smaller circle is at a distance of R/3 from the centre of the larger circle. What is the position of the centre of mass of the plate?

A circular metal plate expends under heating so that its radius increases by k%. Find the approximate increase in the area of the plate, if the radius of the plate before heating is 10cm.

A parallel plate capacitor is charged from a cell and then isolated from it. The separation between the plates is now increased
