A 1200 m B 1300 m C 1400 m D 1500 m Open in App Solution

The correct option is **A** 1200 m

An aeroplane flies 400 m north and 300 m south so the net displacment is 100 m towards

north.

Then it flies 1200 m upward so

r = √ ( 100 ) 2 + ( 1200 ) 2 = 1204 m ≃ 1200 m

The option should be 1204m,because this value mislead one into thinking that net displacement is in upward direction only.

## An aeroplane flies 400 m north and 300m south and then flies 1200 m upwards then net displacement is

An aeroplane flies 400 m north and 300 m south so the net displacement is 100 m towards north. Then it flies 1200 m upwards so, r=sqrt((100)^(2)+(1200)^(2)) =1204m ~= 1200 m The option should be 1204 m, because this value mislead one into thinking that net displacement is in upwards direction only.

The correct Answer is A

Solution

An aeroplane flies 400 m north and 300 m south so the net displacement is 100 m towards north.

Then it flies 1200 m upwards so,

r= (100) 2 + (1200) 2 − − − − − − − − − − − − − √ r=(100)2+(1200)2 =1204m≅1200m =1204m≅1200m

The option should be 1204 m, because this value mislead one into thinking that net displacement is in upwards direction only.

Transcript

hello everyone welcome to this videos in this video we are going to discuss this question and aeroplane flies 400 north and 300 south and then flies 1200 upward displacement is friends in this question first of all a plane flies from this point to not 400 m then South by 300 M get it so that is here hundred no from this point it flies upward get it a word now what we are to find where to find the displacement of this aeroplane displacement must be from this point that we have to find this we are to find this get it friend so by Pathak Rustom Vigyan fine we can find that this will be equal to lete poses oh and this is a so-so a equals to

under root hundred square and and its length is 1200 so plus 1200 square now by solving this what we get we get 1204 but this is not an option so we can see 1200 so here option one is a correct thank you for watching
