The resultant force of 5N and 10N cannot beA) 12 NB) 8 NC) 4 ND) 5 N

Answer»

C) 4 N

Let vector p and q then

|p-q| ≤   |r| ≤  |p+q|

Using this concept

Take p=5 and q= 10 So

|5-10| ≤  |r| ≤ |5+10|

|-5| ≤   |r| ≤   |15|

5 ≤   |r| ≤   15

So range should between 5 to 15 and this range 4 is not present.
