As shown in the figure a particle moves from 0 to A, and then A to B. Find path length and displacement.
A particle moves from A to B and then it moves from B to C as shown in figure. Calculate the ratio between path lenghth and displacement.
A particle moves from A to P and then it moves from P to B as shown in the figure. Find path length and dispalcement.
8. A car goes from one end to the other end of a semicircular path of diameter ‘d’. Find the ratio between path length and displacement.
9. A particle goes from point A to B. Its displacement is X and path length is y. So
A.
B.
C.
D.
Answer : Option C
Explanation :
Path length is always greater or equal to displacement
As shown in the figure a partricle statrs its motion from O to A. And then it moves from A to B.
