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

gravitational force between two objects is (a) F/4 

(d) universal gravitational constant

F ∝ m1m​2 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...

Power of Avinash PA = FA . vA = 10 × 8 = 80 W  The power of Kapil Pk = Fk . vk = 25 × 3 = 75 W  So,...

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 =...

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...

Frictional force is acting opposite to the movement of the book i.e. upwards

Mam as there is the limit of only 150 characters so I couldn't complete the question
