Question

assistant no net force acts on a body falling in a liquid with a velocity equal to the terminal velocity reason the weight of the body is balanced by the upward buoyant force​

Answer 1

Answer:

Hey mate!!

♦Rain drop is falling vertically with constant velocity, then no net force is acting on the rain drop.

♦Net force equals to zero implies, rate of changes of momentum is zero which means momentum is not changing with time.

♦Particle of different masses falls with same acceleration, which is acceleration due to gravity on earth.

♦To change the state (state of rest or state of motion) of a body we need external force. Force = mass x acceleration

♦Hence more force will be required for heavier body.
