If two bodies are in motion with velocity `vec(v)_(1)` and `vec(v)_(2)`:

A

`|v_("rel")| = sqrt(v_(1)^(2) + v_(2)^(2))`

B

`|vec_("rel")| = v_(1) +- v_(2)|`

C

`v_("re") = 0`

D

`v_("rel") gt c` (speed of light)

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`vec(v)_("rel") = vec(v)_(1) - vec(v)_(2)`
`|vec(v)| = sqrt(v_(1)^(2) + v_(1)^(2) + 2v-(1) v_(2) cos (pi - theta))`
