Question

A man goes 10 m10 m towards North, then 20 m20 m towards east then displacement is
​

Answer 1

So, the formula for displacement will be square root of 10 to the power two, added to square root of 20 to the power 2. The answer will be square root of 500. And so, finally the displacement is 22.36.

Answer 2

In the above Question , the following information is given -

A man goes 10 m towards north and then 20 m towards east .

To find -

Find his displacement from the starting point.

Solution -

A man goes 10 m towards north and then 20 m towards east .

Thus , we can say that -

The net displacement of the man is due south east .

The value of the displacement can be calculated as follows -

According to the Pythagoras Theorem -

Displacement = √ ( 10 )² + ( 20 )²

=> Displacement = √ 500

=> Displacement = 10 • √ 5 metres.

Thus , he is 10 • √ 5 m far away from the starting point .

This is the required answer .
