## Conceptual Questions, Vectors and Equailibrium

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
