Question

To get
Resultant of force only along
Y-axis what minimum force
needed to be added along x-axis
AN
30
600 IN
7+
2N​

Answer 1

Answer:

first of all, write the component of all forces.

for force of 4N,

x - component => 4sin30° = 2N(←)

y - component => 4cos30° = 2√3N(↑)

for force of 2N,

x - component => 2cos60° = 1N(→)

y - component => 2sin60° = √3N(↓)

for force of 1N,

x - component => 1cos60° = 0.5N(→)

y - component => 1sin60° = 0.5√3N(↑)

A/c to question,

resultant force only along Y direction, so net force along x direction must be zero.

e.g., force along x direction (→) = force along x direction (←)

1N + 0.5 N ≠ 2N

so, we have to add minimum 0.5 N force forward direction
