Two identical thin rods are welded as shown in the fig. B is midpoint of rod CD. Now the system is cut into two parts through its center of mass M. The part AM weights 4 kg. Find the mass of the other part.

A wire of length (3)/(2)m is cut into two parts. If the length of one of the parts is (2)/(3)m , then find the length of other part.

A wire of length (3)/(2) m is cut into two parts. If the length of one of the parts of the parts is (2)/(3) m, then find the length of other part.

Four thin rods of same mass m and same length L form a square as shown in the figure. M.I. of this system about an axis through center O and perpendicular to its plane is

Two identical square rods of metal are welded end to end as shown in fig (1) . 20 cal of heat flows through it in 4min . If the rods are welded as shown in fig. (2) , the same amount of heat will flow through the rods in

Two uniform thin rods each of length L and mass m are joined as shown in the figure. Find the distance of centre of mass the system from point O

Two uniform thin rods each of length L and mass m are joined as shown in the figure. Find the distance of centre of mass the system from point O

Two uniform thin rods each of length L and mass m are joined as shown in the figure. Find the distance of centre of mass the system from point O

A thin sphereical shell having uniform density is cut in two parts by as plane and kept separated as shown in figure. The point A is the center of the plane section of the first part and B is the center of the plane section of the second part. Show that the gravitational field at A due to the first part is equal in magnitude to the gravitational field at B due to the second part.

Two identical square rods of metal are welded end to end as shown in figure (i), 20 calories of heat flows through it in 4 minutes. If the rods are welded as shown in figure (ii), the same amount of heat will flow through the rods in
