A body is pulled on a horizontal surface with a rope inclined at 30º to the vertical. If the effective force pulling the body along the horizontal surface is 15N, calculate the tension on the rope.
A
30N
B
60N
C
22.5N
D
75N
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
Effective horizontal force = 15N
T = tension on the rope
F\(_x\) = T sin\(\theta\)
15 = T x sin 30º
T = \(\frac{15}{0.5}\) = 15 x 2 = 30N.
