Question

A particle is moving along the sides of an equilateral triangle of side 'a' starting from a verter in clock wise direction (1) Find the maximum possible displacement. (ii) Find the least pos sible displacement when the particle is on opposite side of starting vertex.​

Answer 1

i) Max displacement is along the side. = a

ii) Least displacement when particle is on opposite side = height of a equilateral triangle= $\frac{a\sqrt{3} }2$
