Two spheres of masses m and 2m are separated by distance d. A particle of mass 
is projected straight from 2m towards m with a velocity 
. Which of the following statements is correct?
Text Solution
Verified by ExpertsThe correct answer is:
C
Acceleration between them is zero, where force between 2m and 
is equal to the force
between m and 
or the net force on 
is zero. Suppose this point is P. Now, if velocity 
is less than the value necessary to cross point P, it will retrace its path otherwise not.
