a body of mass 2 kg is sliding with a constant velocity of 4 metre per second on a frictionless horizontal table the force required to keep the body moving with the same velocity is
According to the Newton’s law of inertia (Newton’s First Law of Motion) the body can move with a constant speed only if it is acted upon by the balanced forces. In this question as the body of 2 kg is sliding with a constant velocity the gravitational pull of the earth on it is balanced by the opposing force (friction). So the force balancing the gravitational pull of the earth is equal to its weight = 2 ⨯9.8 N = 19.6 N

MRAK AS BRAINLIST PLS!!!!!
listen given constant velocity so no accelaration .
so a=0
according to newton 2nd law
F=MA
F= 0 N
so it would not require still more FORCE
HOPE BRAINLEST IS MARKED
