Three forces vec F_(1) =5hati+6hatj+7hatk, vec F_(2) =-3hati-2hatj-2hatk and vec F_(3) =-2hati-4hatj-3hatk act on a body. What is the direction of the resultant force acting on the body ?

A particle is acted upon constant forces vec(F)_(1)=4hati+hatj-3hatk and vec(F)_(2)=3hati+hatj-hatk which displace it from a point A=hati+2hatj+3hatk to the point B=5hati+4hatj+hatk . The work done in standard units by the forces is given by ……….......

A force vec(F) = 5hati + 4hatj newton displaces a body through vec(S) = 3hati +4 hatk metre in 3s. Find the power.

Two forces f_(1)=3hati-2hatj+hatk and f_(2)=hati+3hatj-5hatk acting on a particle at A move it to B. find the work done if the position vector of A and B are -2hati+5hatk and 3hati-7hatj+2hatk .

Two forces f_(1)=3hati-2hatj+hatk and f_(2)=hati+3hatj-5hatk acting on a particle at A move it to B. find the work done if the position vector of A and B are -2hati+5hatk and 3hati-7hatj+2hatk .

Two forces f_(1)=3hati-2hatj+hatk and f_(2)=hati+3hatj-5hatk acting on a particle at A move it to B. find the work done if the position vector of A and B are -2hati+5hatk and 3hati-7hatj+2hatk .

A body is moving under the action of two force vec(F_(1))=2hati-5hatj , vec(F_(2))=3hati-4hatj . It's velocity will become uniform under a third force vec(F_(3) given by.
