Q11- A gal moves along the boundary of a square field of
side 20 m in 80 seconds. What will be the magnitude
o displacement at the end of 200 seconds.​

Answer 1

Answer:

total displacement at the end of 200 sec is 40m

Explanation:

She moves 80 m in 80 sec. so in 1 sec she will move 1 m.

so in 200 sec she will move 200 m.

now in 200 m there will be 2 complete round of square i.e. 160m making displacement zero. rest 40 meter will be the displacement.
