Question

The damping force on an oscillator is
directly proportional to the velocity.
The unit of the constant of
proportionality is
(a) kg-ms -1
(b) kg-ms -2
(c) kgs -1
(d) kg-s

Answer 1

c kgmw-1

Explanation:

i believe that the answer must be newton as the si unit of force is always newton i know this too that a newton is Kgms-2 and as the si unit of velocity is ms-¹

solution:

Force ~ velocity

unit of force~ unit of velocity

kgms-2= ms-1 x K (proportionality contsant)

kgms-2 over ms-1 = k

kgm-1 = k

hence the unit must be kgm-1
