Force acting on a particle of mass m mov...

Force acting on a particle of mass m moving in straight line varies with the velocity of the particle as `F=K//V` K is constant then speed of the particle in time t

Text Solution

Verified by Experts

`|vecF| =vA sin theta`
Here, `theta` is angle between `vecv` and `vecA` The particle moves undeflected if `vecF` acts be in positive z-direction. Hence, veloicty should be in negative y-direction.
or `vecV_("min") =-(mg)/A hatj`
