प्रश्न
The position vector particle has a length of 1m and makes 30° with the x-axis. What are the lengths of the x and y components of the position vector?
उत्तर
Given,
Length of position vector = 1 m
Angle made with x axis = 30
Solution:
Length of X component (OB) = OA cos θ
= 1 × cos 30°
= `sqrt3/2` (or) 0.87 m
Length of Y component (AB) = OA sin θ = 1 × sin 30°
= `1/2` = 0.5 m.
