Type: MCQ-numerical-Medium-Class 11
Three forces acting on a body are shown in the figure. To have the resultant force only along the y-direction, the magnitude of the minimum additional force needed is -
A
√3/4 N
B
√3 N
C
0.5 N
D
1.5 N
Correct Answer
Option C
Detailed Explanation
To have the resultant force only along the y-direction, the x-components of the forces must cancel out. Calculating the required additional force using vector addition gives 0.5 N.
