Question
A body of mass M is acted upon by a force F and the acceleration produced is a. If three coplanar forces each equal to F and inclined to each other at 120o act on the same body and no other forces are acting. The acceleration produced will be:
Options
A.√2 a
B.a/
C.3a
D.zero
Solution
Due to symmetry we can say net force on body M is O.
∴ acceleration is O.
