Question

When two forces are combined, the magnitude. of the resultant force depends on the angle between the two forces. Which of the following cannot be the magnitude of the resultant force when forces of magnitude 3 N and 7 N are combined? (A) 3 N (B) 4 N (C) 7 N (D) 9 N

Answer 1

Answer:

(A)3N

Explanation:

Maximum resultant force=3N+7N =10N(only possible when angle b/w them is 0°)

Minimum resultant force=7N-3N=4N(only possible when angle b/w them is 180°)

the resultant force must be b/w 4N and 10N.

Having a look at the options, only option (A) 3N is not b/w 4N and 10N.
