Question

Q#3 A Vector A = 50 unit, its angle (theta) is 30° with x-axis then its component perpendicular
to x-axis will be:
(a)-5 Unit
(5)5 Unit
(c)50 Unit
(d)25 Unit
​

Answer 1

A = 50units

∅ = 30°

Component perpendicular to x-axis is component along y-axis which is Asin∅

Asin∅ = 50×sin30 = 50×1/2 = 25units

The correct option is (d)25units
