The force on 4 kg mass is 20 N, & that on 2kg mass is 2 N in the opp. direction. u=0.5 between these two masses. Find the frictional force
There is no friction between 4 kg mass and ground.

The gravitational force between two objects is F. If masses of both objects are halved without changing distance between them,
gravitational force between two objects is (a) F/4

How does the force of attraction between the two bodies depend upon their masses and distance between them?
F ∝ m1m2 and F ∝ 1/d2 This hypothesis is not correct. The two bricks, like a single body, fall with the same speed to reach the ground at the same time...

Avinash can run with a speed of 8 m s–1 against the frictional force of 10 N, and Kapil can move with a speed of 3 m s–
Power of Avinash PA = FA . vA = 10 × 8 = 80 W The power of Kapil Pk = Fk . vk = 25 × 3 = 75 W So,...

Two objects of masses 100g and 200g are moving along the same line and direction with velocities of 2 ms -1 and 1 ms -1
Mass of one of the objects, m1 = 100 g = 0.1 kg Mass of the other object, m2 = 200 g = 0.2 kg Velocity of m1 before collision, v1 =...

Calculate the formula unit masses of ZnO, Na2O, K2CO3, given masses of Zn = 65u, Na = 23u, K = 39u, C = 12u, and O = 16u.
Formula unit mass of ZnO = Atomic mass of Zn + Atomic mass of O = 65 + 16 = 81 u Formula unit mass of Na2O = 2 × Atomic mass...

Suppose your writing desk is tilted a little. A book kept on it starts sliding down. Show the direction of frictional force acting on it.
Frictional force is acting opposite to the movement of the book i.e. upwards
