Question

Two particles A and B are moving along the same
straight line in mutually opposite directions with
speed 10 ms-1 and 20 ms- respectively. At t = 0
their separation is shown in the given figure. They
will meet at
A
B
300 m
(2) t = 15 s
(1) t = 30 s
(3) t = 10 s
(4) t = 12.5 s​

Answer 1

Answer:

10 seconds

Explanation:

u can take relative velocity of A with respect to be which is 30 m/s

with 30 m/s a body can cover 300m in 10 seconds
