Question

Two cars A and B are moving with uniform velocity
as shown in figure. The shortest distance between
two particles will be :

(1) 2m
(2) 2/5 m
(3) 4/5m
(4) 5/5 m​

Answer 1

I think it may be 2m .....

Answer 2

Answer:

The shortest distance is 10 m.

Explanation:

The shortest distance is the perpendicular distance.

So, B will reach at point O after time 40/20 = 2 s

At t=2s A will be at 10*2 = 20 m. Means 10 m behind from O.

So the shortest distance between A and B will be after 2 s when they are exactly in a line and the distance between them is 10 m.
