Question

Two forces each of magnitude 10N acting on a body, if the forces are inclined at 30° and 60° with x axis, the X component of the resultant is? A)10N B)136.6N C)1.366N D)13.66N

Answer 1

Hope this should help out

Answer 2

Answer:

13.6N

Explanation:

X component of a vector = cosine of the vector

X component of force = Fcos30⁰ + Fcos60⁰ (Since two forces are acting on it)

= 10 ( √3 + 1) ÷ 2

5 ( 1.72 + 1)

5 × 2.72

= 13.6N
