A particle moves on a circular path of radius R as shown in figure. The distance travelled and displacement of the particle from point A to point C respectively are
A
BπR, 2R
C
DπR, πR
Ans 1:
Class : Class 7
The answer is option c. The circumference of a circle is 2πr. A to C is only half of the circle = 2πr/2 = πr
Displacement is the shortest way possible. In this case, the shortest way is just directly walking from A to C in a straight line, which is 2r
