An object falling through a fluid is observed to have acceleration given by ` a= g- bv` where ` g= gravitational acceleration and (b) is constant. After a long time of rlease. It is observed to fall with constant speed. What must be the value of constant speed ?

Text Solution

Verified by Experts

When an object is falling with constant speed. V is constant , then
`a=(dv)/(dt)=0`
or `g-bv=0`
or `v=(g)/(b)`
