Two masses 5 kg and 3 kg are suspended with the help of massless inextensible strins as shown in the figure. Calculate `T_1` and `T_2` when whole system is going upwards with acceleration = `2ms^2` (use `g=9.8 ms^-2)`

A man weighs 70 kg. He stands on a weighing scale in a lift which is moving? upwards with a uniform acceleration of 5 ms^-2 .

What force is required to produce an acceleration of 2ms^-2 on a body of mass 10 kg?

A man weighs 80 kg. He stands on a weighing scale in the lift, which is moving upward with a uniform acceleration of 5 ms^-2 what whould be the reading on the scale? (g = 10 m//s^2) .

Mass of an object is 10 kg. What is the weight on the earth (g = 9.8 ms^-2) ?

V-I graph for a mettalic wire at two different temperatures T_1 and T_2 is as shown in figure. WHich of the temperatures T_1 and T_2 is higher and why.

An automobile vehicle has mass of 1,500 kg. What must be the force between vehicle and the road if vehicle is to be stopped with negative acceleration of 1.7 ms^(-2) ?

A 20 g bullet pierces through a plate of mass M_1 = 1 kg and then comes to rest inside a second plate of mass M_2 = 2.98 kg as shown in figure. It is found that the two plates, initially at rest, now move with equal velocities. Find the percentage loss in the initial velocity of the bullet when it is between M_1 and M_2 Neglect any loss of material of the plates, due to action of bullet.

A small stone, of mass 0.2 kg, tied to a massless, inextensible string, is rotated in vertical circle of radius 2 m. if the particle is just able to complete the vertical circle, what is its speed at the highest point of its circular path? How would this speed get effected if the mass of the stone is increased by 50%? (Take g = 10 ms^(-2) )
