Question

IV. 1. The position vectors particle has length Im and makes 30° with the x-axis. What are the lengths of the x and y components of the position vector?
​

Answer 1

Answer:

Length of position vector = 1 m Angle made with x axis = 30 Length of X component (OB) = OA cos θ = 1 x cos 30° = √ 3 2 32 (or) 0.87 m Length of Y component (AB) = OA sin θ = 1 x sin 30° = 1 2 12 = 0.5 m.Read more on Sarthaks.com - https://www.sarthaks.com/891987/the-position-vector-of-the-particle-has-length-1-m-and-makes-30-with-the-x-axis
