Question

A displacement time graph for two particle A and B are straight lines inclined at angles of 30°and60° with the te axis. The ratio of velocities vA:vB is ________.
a)1:2 b)1:√3
c)√3:1 d)1:3​

Answer 1

Answer:

1:3

Explanation:

As velocity v= dt  dx   =slope of x−t graph.

so V  A  :V B

​   =slope  A  :slope B

​   =tan30 0  :tan60  0  =1 : 3

​   =1:3
