Question

1. The displacement time graph for two particles A
and B are straight lines inclined at angles of 30°
and 60° with the time axis. The ratio of velocity of
VA: Vg is
B
$
<600
R300
300
(2) 1:13
(1) 1:2
(3) 3:1
(4) 1:3​

Answer 1

Answer:

Explanation:

Velocity = Slope of the line formed in displacement v/s time graph = Tanθ

Va : Vb = Tan30 : Tan45 = (1/√3) : 1 = 1 : √3

Ratio of velocities of A:B is 1 : √3
