A force of 6 kg-wt and another of 8 kg-wt are applied together at a point. Which of the following could be the magnitude of their combined resultant?

1. 1 kg wt
2. 11 kg wt
3. 15 kg wt
4. 20 kg wt

Correct answer: 11 kg wt

Solution

The magnitude of the resultant of two vectors of magnitudes 6 and 8 can vary from \(|8-6|=2\) to \(8+6=14\). Among the options, only 11 lies in this range. Hence, 11 kg-wt is possible.
