[" Q.No."24" Three forces "],[F1=5i+6j+7k,F2=-3i-2j-2k" and "],[F3=-2i-4j-3k" act on a body."],[" What is the direction of the "],[" resultant force acting on the "],[" body? "]

Two vector forces (2hat i+hat j+3hat k) and (3hat i+hat j-hat k) are acted on a particle.Find the angle between the resultant force to the XY- plane.

If 2i-j+k and i-3j-5k and 3i-4j-4k form a triangle, what type of triangle is it ?

The force f = 2i + 2j - k acting at a = I - 2j + k is displaced to a unit distance on z-axis (Oz = 1) direction. The magnitude of the work done is

If the resultant of three forces vec F_1=p hat i+3 hat j- hat k , vec F_2=6 hat i- hat k and vec F_3=-5 hat i+ hat j+2 hat k acting on a parricle has magnitude equal to 5 units, then the value of p is a. -6 b. -4 c. 2 d. 4

If the resultant of three forces vec F_1=p hat i+3 hat j- hat k , vec F_2=6 hat i- hat k and vec F_3=-5 hat i+ hat j+2 hat k acting on a parricle has magnitude equal to 5 units, then the value of p is a. -6 b. -4 c. 2 d. 4

If a = 3i - 2j + k, b = 2i - 4j - 3k, c = -i + 2j + 2k then a + b + c =
