Analysis Questions
1. If two equal vectors of 5 N are at 90° to each other, what will be the magnitude and
direction of a third vector which gives a zero resultant?
The components of reultant vector along horizontal axis
2. What is the minimum number of unequal vectors that can be added to get a zero resultant?
Give a reason for your answer.
3. 2425: Using values from any one of the trials, express F1, F2, the resultant R and the
equilibrant E in i, j, k notation. Convert the mass in grams to force in Newtons.
Fâ=100g. 1kg = 0.1kg - 9.8m/s2 = 0.98N
F2 =
R =
E =
4. Write the sources of error and conclusions for this experiment.
