Question

A particle travels from point A to Calong the path ABC as shown in figure. The ratio of distance travelled to the magnitude of displacement is B. a -c А O 1:2 O 3:1 2:1 O 1:1​

Answer 1

Distance travelled = 2a

Displacement by pythagoras theorem=$\sqrt{2}a$

hence ratio=$2a/\sqrt{2} a$ = $\sqrt{2} \ :1$ {Note that you have to rationalise the denominator }
