Question

If a box is pulled by a rope making an angle with surface then horizontal component of force is equal to

Answer 1

Ans:-F cos theta.....

Answer 2

F cosθ

If a box is pulled by a rope making an angle with surface then horizontal component of force is equal to F cosθ.

• You can use the sine function to calculate the vertical component of force and the cosine function to calculate the horizontal component of force.

• Since the triangle's horizontal component is absent, the horizontal leg is 0 and the cosine is also 0.
• Think about the unit circle and the angle itself. The angle does not have a horizontal component. The cosine of 90 degrees is zero because the angle's horizontal component is zero.
