A bob weighing ` 0.06 kg` hangs vertcally at the end of a sting ` 0.30 m` long. Find the force which when applien horizontally, will pull the bob ` 0. 10 m` aside from its initial psition.

A bob weighing 50 gram hangs vertically at the end of a string 50 cm long . If 20 gram force is applied horizontally, by how much distance the bob is pulled aside from its initial position when it reaches in equilibrium position?

A metal bob of mass 0.6 kg is attached to the end of a string of length 1 m and the bob is whirled in a horizontal circle with a uniform speed of 12 m/s. What is the centripetal force acting on the bob ? If the speed of the bob is 5 m/s calculate the tension in the string.

A bob tied to the end of a string of length 2m, other end of which is fixed at a point in a vertical wall at a point O. The bob is imparted a vertical downward velocity of 5 m//s when the string is horizontal and swings in a vertical plane. Find the angular displacement of the bob from its initial position, when the string breaks. Given that the tensile strength of the string is twice the weight of the bob. Take g=10 m//s^(2)

Spring is mounted as shown in figure. By attaching a mass to the free end and pulling side ways, we determine that the force is proportional to the displacement a force of 4N causing a displacement of 0.02 m. We attach a 2kg body to the end, pull it aside through a distance of 0.04m , and then released. Find the velocity adn acceleration when the body has moved half way in toward the central from is initial position.

A uniform light spring has unstretched length of 3.0 m. One of its end is fixed to a wall. A particle of mass m = 20 g is glued to the spring at a point 1.0 m away from its fixed end. The free end of the spring is pulled away from the wall at a constant speed of 5 cm/s. Assume that the spring remains horizontal (i.e., neglect gravity). Force constant of spring = 0.6 N / cm. (a) With what speed does the particle of mass m move? (b) Find the force applied by the external agent pulling the spring at time 2.0 s after he started pulling.

Mass of the bob of a pendulum is 100g and the length of the string is 1m . The bob is initially held is such a way that the string is horizontal . The bob is then released. Find the kinetic energy of the bob when the string makes an angle of (i) 0^@ with vertical

A bob of mass 0.25 kg hung from a ceiling of a room by a string 1 m long is set into oscillation. The speed of the bob at its mean position is 1.5 m/s. What is the trajectory of the bob if the string is cut when the bob is at its mean position.
