A particle acted by constant forces 4hat i+hat j-3hat k and 3hat i+hat 9-hat k is displaced from point hat i+2hat j+3hat k point 5hat i+4hat j+hat k .find the total work done by the forces in units.

A force vec(F) = hat(i) + 3hat(j) + 2hat(k) acts on a particle to displace it from the point A (hat(i) + 2hat(j) - 3hat(k)) to the point B (3hat(i) - hat(j) + 5hat(k)) . The work done by the force will be

Work done by a force F on a body is W = F .s, where s is the displacement of body. Given that under a force F = (2 hat I +3 hat j +4 hat k) N a body is displaced from position vector r_1 = (2 hat I +3 hat j + hat k) m to the position vector r_2 = (hat i +hat j+ hat k) m. Find the work done by this force.

A force vec(F) = hat(i) + 3 hat(j) + 2 hat(k) acts on a particle to displace it from the point A (hat(i) + 2hat(j) - 3 hat(k)) to the point B(3hat(i) - hat(j)+5hat(k)) . The work done by the force will be
