Kinematics Question 108
Question: If the resultant of n forces of different magnitudes acting at a point is zero, then the minimum value of n is [SCRA 2000]
Options:
A) 1
B) 2
C) 3
D) 4
Correct Answer: C If vectors are of equal magnitude then two vectors can give zero resultant, if they works in opposite direction. But if the vectors are of different magnitudes then minimum three vectors are required to give zero resultant.
