Physics Systems of Particles and Rotational Motion JEE Main

Three stationary particles of masses are under the action of the same constant force for the same time. If , the variation of momentum with time for each will be correctly shown as

(A)three distinct diverging straight lines from the origin, steepest for A
(B)three distinct diverging straight lines, steepest for C
(C)three horizontal (constant) lines
(D)a single common straight line through the origin, for A, B and C togetherCorrect

Answer: (D)

Solution

— the momentum gained under a given constant force for a given time depends only on and , not on the
