A person travels towards north by 4 m and then (A) Always = 1 (B) Always < 1 turns to west and travels by 3 m. The distance and (C) Always > 1 (D) May be 1 displacement are (A) 7 m and 5 m (B) 7 m and 7 m 2. Which of the following statement is not true? (C) 7 m and 1 m (D) 7 m and 3.5 m (A) If displacement covered of a particle is zero, then distance covered may or may not be zero 8. A particle is moving along a circle such that it (B) If the distance covered is zero then the completes one revolution in 40 seconds. In displacement must be zero displacement 2 minutes 20 seconds, the ratio is (C) The numerical value of ratio of displacement to distance distance is equal to or less than one 1 (A) 0 (B) (D) The numerical value of the ratio of velocity to 7 speed is always less than one 2 1 (C) (D) 7 11 3.
