Question

An object moving in a circular path and covered 3/4 distances on the permiter of the path to reach from A to B. if 'r' is radius of the circular path then the ratio between distances travelled and displacement by the object between A and B is?​

Answer 1

Answer:

Explanation:

here distance travelled by an object= 3/4 × 2πr

then join point A with center

and join point B with center

and join point A and B

you find that triangle AOB is right angled isosceles triangle

AB is its hypotenuse

Displacement AB =√2 × r

According to Question ratio is

=3/2 πr : √2 × r

= 3/2 π : √2

= 3π : 2√2
