This page consists of conceptual questions on Vectors and Equilibrium included in the course of First Year Physics for all BISE Khyber Pakhtunkhwa (KPK).
Q 1 
Explain with the help of an example, what is the range of possible values of the resultant of two vectors?
see answer

Q 2 
What is the minimum number of unequal vectors to result into a null vector? Explain with the help of a diagram.
see answer

Q 3 
The resultant of two vectors, one is double in magnitude than the other, is perpendicular to the smaller force. What is the angle between the two vectors? see answer 
Q 4 
Explain how cranes are able to lift very heavy load without toppling?
see answer

Q 5 
The gravitational force acting on a satellite is always directed towards the center of the earth. Does this force exert torque on the satellite?
see answer

Q 6 
Explain why do buses and heavy trucks have large steering wheels?
see answer

Q 7 
A point object acted on by forces 4N, 5N and 6N in equilibrium. If the 6N force is removed, what is the resultant force on the object? see answer
