Question 1

Forces of 100 N and 200 N act on an object in the same direction along the same line. What is the resultant force?

A 100 N B 300 N C 200 N D 20 000 N

The right answer is the one marked above.

300 N. The resultant of two collinear forces in the same direction is their sum: 100 N + 200 N = 300 N.

100 N or 200 N is just one of the forces, not the resultant. Forces are not multiplied — they are added.
