Question: A force of 50 N is applied at an angle of 60° to the horizontal. What is the horizontal component of the force? (2020)

Options:

Correct Answer: 43.3 N

Exam Year: 2020

Solution:

Horizontal component = F × cos(θ) = 50 N × cos(60°) = 50 N × 0.5 = 25 N.

A force of 50 N is applied at an angle of 60° to the horizontal. What is the horizontal component of the force? (2020)

A force of 50 N is applied at an angle of 60° to the horizontal. What is the horizontal component of the force? (2020)

Step 1: Identify the total force applied, which is 50 N.
Step 2: Identify the angle at which the force is applied, which is 60°.
Step 3: Use the formula to find the horizontal component of the force: Horizontal component = F × cos(θ).
Step 4: Substitute the values into the formula: Horizontal component = 50 N × cos(60°).
Step 5: Calculate cos(60°), which is 0.5.
Step 6: Multiply 50 N by 0.5: 50 N × 0.5 = 25 N.
Step 7: The horizontal component of the force is 25 N.
