37, Hf the gravitational force between two objectswereproportional to 1/R (and not as 1/R2), where R isthe distance between them, then a particle in acircular path (under such a force) would have itsorbital speed v, proportional to

Answer»

Given here:

F∝1/Ror,F =kRNow, when one of the particles goes around the other then it is acted upon by a centripetal force given by:

Fcentri= mv2/Rnow,

mv2/R = kR

v =R√(k/m)orv∝ R
