Question

A particle is moving in circles of diameter 30 m find distance and displacement for 1,1.5,2 and 2.5 round

Answer 1

$\huge{\purple{\underline{\underline{\bf{\pink{Answer:-}}}}}}$

Displacement is the vector drawn from the initial position to the final position, and its magnitude is equal to the shortest distance between the initial and final positions.

i. Hence, displacement is equal to the diameter of the circle = 2 R.

ii. As initial and final positions are same, i.e., displacement will be zero.

b; Distance is the length of the path travelled by the particle. Hence, distance traveled in case (i) will be equal to πR.

Hence the distance travelled in case (ii) will be equal to 2πR

Answer 2

Answer:

${\huge{\underline{\underline{\texttt{\orange{Answer:-}}}}}}$

the occupation by a submerged body or part of a body of a volume which would otherwise be occupied by a fluid.

i. Hence, displacement is equal to the diameter of the circle = 2 R.

ii. As initial and final positions are same, i.e., displacement will be zero.

b Distance is the length of the path travelled by the particle. Hence, distance traveled in case (i) will be equal to πR.

Hence the distance travelled in case (ii) will be equal to 2πR
