Question

Please answer....3rd question.​

Answer 1

Answer: DISPLACEMENT IS √2R

              DISTANCE IS πR/2

Explanation:

DISPLACEMENT: IT IS THE SHORTEST DISTANCE TRAVELLED

DISTANCE:TOTAL PATH COVERED

SO DISTANCE COVERED IN 1/4th OF CIRCLE IS 2πR/4=πR/2

BUT DISPLACEMENT IS $\sqrt{R^{2}+R^{2} }$=√2R

HOPE IT WILL HELP YOU..............

THANK YOU.

Answer 2

Answer:

DISPLACEMENT IS √2R

DISTANCE IS πR/2
