The variation of quantity A with quantity B is plotted in the fig. Describes the motion of a particle in a straight line. (a) Quantity B may represent time. (b) Quantity A is velocity if motion is uniform. (c) Quantity A is displacement if motion is uniform (d) Quantity A is velocity if motion is uniformly accelerated.A. (a) Quantity (B) may represent time.B. (b) Quantity (A) is velocity if motion is uniform.C. (c ) Quantity (A) is displance if motion is uniform.D. (d) Quantity (A) is velocity if motion is uniformly accelerted.

Answer» Correct Answer - A::C::D
Quantity (B) may represent time. Thus, option (a0 is true, If motion is uniform, the velcoity-time graph showul be a straight line parallel to tiem axis. Theus, quantiy (A) cannot be a velocity Thus, Option (b) is wrong. If motion os uniform , the velocity is constant. The displacement-time graph is a straight line with positive slope. theus, quantity ()A is displacement. If motion is uniformly accelerated, the accelerationis constant. The velocity-tieme graph is a straight line with positive slope. Thus, quanitiy (A) is vellocity.
