Q
Q: A force of 15 N is applied at an angle of 30° to the horizontal. What is the horizontal component of the force? (2020)
Solution:
Horizontal component = F × cos(θ) = 15 N × cos(30°) = 15 N × √3/2 ≈ 12.99 N.
Steps: 7
Show Steps
Step 1: Identify the total force applied, which is 15 N.
Step 2: Identify the angle at which the force is applied, which is 30°.
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 = 15 N × cos(30°).
Step 5: Calculate cos(30°). The value of cos(30°) is √3/2.
Step 6: Substitute cos(30°) into the equation: Horizontal component = 15 N × √3/2.
Step 7: Calculate the horizontal component: 15 N × √3/2 ≈ 12.99 N.
