Answer;
- No, Two vectors of unequal magnitude can never sum to zero.
Explanation;
-Two vectors of equal magnitude that are pointing in opposite directions will sum to zero.
-Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero.
- If they point in different directions, then you can always decompose one vector into two components: one along the other vector and one perpendicular to the other vector. In this case, the perpendicular component can never be eliminated.

Answer:
5000 N/m
Explanation:
Hooke's law for the spring is
where here we have
F = 100 N is the force applied to the spring
k is the spring constant
is the stretching of the spring with respect to its equilibrium position
Solving the equation for k, we find the spring constant:
