Question

a particle moves along a circle of radius r. it starts from a and moves in anticlockwise direction. calculate the distance travelled by the particle (a) from Ato B (b) from A to B (b) from A to C (c) from A to D (d) in one complete revolution. Also calculate the magnitude of displacement in each case
plz solve this is urgent​

Answer 1

you can solve like this

particles move along a circle = circumference of circle = 2πr

and radius is = 1/2 of diameter

okkkk
