Question
Three coplanar forces of 5 N, 6 N and 7 N act on an object. Which force could not be the resultant of these three forces?
A. 0 N
B. 11 N
C. 13 N
D. 19 N
Markscheme
D
Examiners report
Most candidates recognised that 19N could not be achieved with these three forces but a sizeable proportion at both levels believed that they could not be added to total zero.
