Question

A body covers 3/4th of a circular path of diameter 12 m in 100 sec. What are the values of displacement and velocity?

Answer 1

Answer:

circumference of a circle is 2 pie r

so distance travelled will be the total distance travelled btw final and initial point and as it travelled 3 quarters therefore it will be 3/4th of circumference.

displacement will be actual distance between final and initial point it doesn’t count the total path covererd. It is just the distance btw the initial and final point.

but in this case it only mentions that the body quarters of its circular path… it will be equal to distance travelled. it it was asked body made 2 or 3 rounds from a certain point, then distance travelled was 2*2pie*r and displacement would be zero…..
