Rotational Motion

269442 A door can just be opened with10 N force on the handle of the door. The handle is at a distance of 50 cm from the hinges. Then, the torque applied on the door (in Nm ) is

1 5
2 10
3 15
4 20
Rotational Motion

269443 A particle of mass m is projected with an initial velocity u at an angle θ tohorizontal.The torque of gravity on projectile at maximum height about the point of projection is

1 mgu2sin2θ2
2 mgu2sin2θ
3 mgu2sinθ2
4 12mu2sin2θ
Rotational Motion

269444 A uniform rod is4 m long and weights 10 kg. If it is supported on a knife edge at one meter from the end, what weight placed at that end keeps the rod horizontal.
