Two particles move along x-axis in the same direction with uniform velocities `8 m//s` and `4 m//s`. Initially the first particle is 21 m to the left of the origin and the second one is 7 m to the right of the origin. The two particles meet from the origin at a distance of

A

35 m

B

32 m

C

28 m

D

56 m

Text Solution

Verified by Experts

The correct Answer is:
A
`x + 21 = u_(1)t, x - 7 = u_(2)t`
