A spaceship is sent to investigate a planet of mass M and radius R. While hanging motionless in space at a distance 5R from the centre of the planet, the spaceship fires an instrument package of mass m, which is much smaller than the mass of the spaceship. The angle θ for which the package just grazes the surface of the planet is

A massless string is wrapped around a hollow cylinder having mass m and radius r. The cylinder is kept on a rough horizontal surface (coefficient of friction is mu). A constant force F is applied as shown in the figure. In case of pure rolling, the friction force acting on the bottom most point of the cylinder is

Let I be the moment of inertia, of a uniform square plate about an axis AB that passes through its center and is parallel to two of its sides. CD is a line in the plane of the plate that passes through the center of the plate and makes an angle θ with AB as shown in the figure. The moment of inertia of the plate about the axis CD is then equal to
