Question

A particle starting from one vertex of a rectangle of sides l,b revolving along
the sides. Find the maximum displacement ?​

Answer 1

Answer:

distance between a and d

Explain:

let us suppose rectangle as ABCDE if it covers all sides the displacement will be zero so the maximum magnitude of displacement will be of three sides so the displacement between three side is the distance between a and d.

Answer 2

Concept introduction:

Displacement is the shortest distance covered from initial to final point.

Explanation:

Given that, a particle starting from one vertex of a rectangle of sides l, b revolving along the sides.

We have to find, the maximum displacement.

According to the question,

The maximum displacement of the particle will be along the diagonal of the rectangle that is equal to $\sqrt{l^{2} +b^{2} }$.

Final Answer:

Maximum displacement of the particle will be equal to $\sqrt{l^{2} +b^{2} }$.
