State whether three forces of magnitude 1 dyn, 2 dyn and 3 dyn acting simultaneously on a body can keep it in equilibrium.

State whether three forces of magnitude 1 dyn, 2 dyn and 3 dyn acting

1.	State whether three forces of magnitude 1 dyn, 2 dyn and 3 dyn acting simultaneously on a body can keep it in equilibrium.
Answer» Solution :If 1 DYN and 2 dyn forces act on a body in parallel, then the resultant on the body becomes (1+2) dyn or 3 dyn. Now if the given 3 dyn force ACTS on the body ALONG the same line of the resultant force but in opposite direction to it, then the resultant force on the body becomes zero. HENCE the body will be in equilibrium.
