A particle is acted upon by constant forces `vecF=-2hati+3hatj+4hatk and vecF_(2)=- hati+2hatj-3hatk` is distanced from the point A (2,1,0,) to the point B(-3,-4,2) Find the work done by forces.

A particle acted upon by constant forces 4hati +hatj- 4 hatk and 3hati + hatj - hatk is displacment from the point hati+ 2hatj+ hatk to point 5hati + 4hatj +hatk .Total work done by the forces in SI unit is :

A particle is acted upon by constant forces 4hati +hatj - 3hatk and 3hati + hatj -hatk which displace it from a point hati + 2hatj + 3hatk to the point 5hati + 4hatj + hatk . The work done in standard units by the forces is given by:

The resultant of the forces vecF_(1)=4hati-3hatj and vecF_(2)=6hati+8hatj is

If vecF=2hati+3hatj-hatk and vecr=hati-hatj+6hatk find vecrxxvecF

A paticle acted on by constant forces 4hati+hatj-3hatk and 3hati+hatj-hatk is displaced from the point hati+2hatj+3hatk to 5hati+4hatj+hatk . Find the work done

If the constant forces 2hati-5hatj+6hatk and -hati+2hatj-hatk act on a particle due to which it is displaced from a point A (4,-3,-2) to a point B (6,1,-3), then the work done by the forces is

If vecF=hati+2hatj-3hatk and vecr=2hati-hatj+hatk find vecrxxvecF
