Physics Laws of Motion

Two blocks of masses 6 kg and 4 kg are connected by a rope of mass 2 kg are resting on a frictionless floor as shown in the following figure. If a constant force of 60 N$$ is applied to 6 kg block, then the tension in the rope at points A,B$$ and C$$ are, respectively, given by

The surface are frictionless, the ratio of T$$ l and $T_2$ ${}_{}$ is 

An insect of mass m = 2g is inside a vertical drum of radius 1m that is rotating with an angular velocity of 10 rad/s. If the insect does not fall off then the minimum coefficient of friction is

A car is moving in a circular horizontal track of radius 10 $m$ $$ with a constant speed of 10 $m/s$ $$ . A bob is suspended from the roof of the car by a light wire of length 1.0 $m$ $$ . The angle made by the wire with the vertical is

The ratio of tensions  $T_A:T_B$ in two strings $A$ and $B$ supporting a log of mass $M$  as shown in figure is

In case of horse pulling a cart , the force that causes the horse to move forward is the force that

Two balls each of mass 1kg moving in opposite directions with speed 15m/s  collides and rebounds with the same speed. The magnitude of impulse imparted to each ball due to other is

For the arrangement shown in figure, the tension in the string to prevent it from sliding down, is (g = 10 m/s²)

The kinetic energy of a body varies directly as square of time elapsed. The force acting varies directly as

A ball is projected from ground with initial momentum p at an angle θ . What is the magnitude of net change in linear momentum when it reaches at maximum height of journey?
