Question

Two vectors, 3 N to the north and x, produce zero resultant. Calculate x.

a) 3 N
b) 6 N
c) 0 N
d) 9 N

Answer 1

The vector x that cancels out the 3 N northward vector must be 3 N directed southward to produce a zero resultant.

Step-by-step explanation:

When two vectors produce a zero resultant, the vectors are equal in magnitude but opposite in direction. Given that the first vector is 3 N to the north, the vector x that produces a zero resultant would need to be 3 N to the south. Therefore, the magnitude of x is 3 N, as it has to exactly cancel out the northward force.
