Question

Sunil and Rohit start at one end of a street, the origin and run to the other end, then head back. On the way back, Sunil is ahead of Rohit. Which statement is correct about the distances run and the displacements from the origin before reaching the origin?

• A. Sunil has run a greater distance and his displacement is greater than Rohit's
• B. Rohit has run a greater distance and his displacement is greater than Sunil's
• C. Sunil has run a greater distance but his displacement is lesser that Rohit's
• D. Rohit has run a greater distance but his displacement is lesser than Sunil's

Answer 1

Answer: (C)

Sunil has run a greater distance but his displacement is lesser that Rohit's

Before reaching origin, distance travelled by Sunil is more than Rahul since he is ahead of Rohit. But displacement of Rohit is more as he is far from the origin than Sunil.
