A rod of XY of weight 16N is hinged at X and supported by a string at Y. The string is at angle 30°. The tension in the string is 16N.

What is the horizontal component of the force acting at X?
(A) 8N
(B) 9N
(C) 14N
(D) 16N

Option C) 14N

Explanation:

we know that

To find out the horizontal component of the force acting at X, multiply the tension in the string by the cosine of 30 degrees

so

Round to the nearest whole number
