Question 16. A particle starting from the origin (0, 0) moves in a straight line in the (x, y) plane. Its coordinates at a later time are the path of the particle makes with the x-axis an angle of (a) 300 (b) 450 (c) 600 (d) 0 Answer
Correct option is C) Particle starts moving from (0,0) and goes till (3,3). So total displacement along x axis is 3 unites and along y axis is 3 units. We know that: ⇒tan(θ)=xy ⇒tan(θ)=33 ⇒tan(θ)=3 ⇒θ=3π=600
