Question

Which of the following pair of concurrent forcess can not have a resultant of 4N?

Answer 1

Answer:

3N and 8N

Explanation:

3N & 8N will give Fmax = 8 + 3 = 11N & Fmin = 8 - 3 = 5N .

The resultant force always lies between maximum & minimum value & 4 is outside the range.  So 3N and 8N cannot give resultant as 4N.
