A body placed in free space, is simultaneously acted upon by three forces `vec(F_(1)),vec(F_(2)) " and " vec(F_(3))`. The body is in equilibrium and the forces `vec(F_(1)) " and "vec(F_(2))` are known ot be 36 N due north and 27 N due east respectively. Which of the following best describes the force `vec(F_(3))`?

Two forces vec(F_(1)) and vec(F_(2)) are acting at right angles to each other , find their resultant ?

When force vec(F_(1)), vec(F_(2)),vec(F_(3))"…..."vec(F_(n)) act on a particle , the particle remains in equilibrium . If vec( F_(1)) is now removed then acceleration of the particle is

When force vec(F)_(1),vec(F)_(2),vec(F)_(3) are acting on a particle of mass m , the particle remains in equilibrium. If the force vec(F)_(1) is now removed then the acceleration of the particle is :

Three forces (vec(F)_(1), vec(F)_(2), vec(F)_(3)) are acting an a particle moving vertically up with constant speed. Two force vec(F)_(1)=-10hat(j)N , and vec(F)_(1)=-6hat(i)=8hat(j) , N are acting an particle on acting on particle respectively find vec(F)_(3) .

A body is at rest under the action of three forces, two of which are vec(F)_(1)= 4hat(i), vec(F)_(2)= 6hat(j) , the third force is

A body is at rest under the action of three forces, two of which are vec(F)_(1)= 4hat(i), vec(F)_(2)= 6hat(j) , the third force is

A moving perticle of mass m is acted upon by five forces overset(vec)(F_(1)),overset(vec)(F_(2)),overset(vec)(F_(3)),overset(vec)(F_(4)) and overset(vec)(F_(5)) . Forces overset(vec)(F_(2)) and overset(vec)(F_(3)) are conservative and their potential energy funcations are U and W respectively. Speed of the particle changes from V_(a) to V_(b) when it moves from position a to b . Choose the correct option :
