Answer:

86.6Nm(j)

Explanation:

we know,

w=Fd

w=17.32*5

w=86.6Nm.

as we know the distance but we doesnot know the exact force .becauseit acts at an angle.This mean the orginal force of 20N is essentially split up in 2 direction in along axis of displacement ,and perpendincular direction that occur at 30degree angle.

the resultant displacement of object is along a line inclined by 30 degrees of that orginal plane ,then the force acting in the direction of that displacement equal to 20*cos30.I.e,17.32 .
