Q3  Out of the following set of physical quantities, the vector quantities are

  • (a) Area and area vector 
  • (b) Impulse and area vector
  • (c) Gravitational Potential and force 
  • (d) Kinetic Energy and Velocity

  • (d) Kinetic Energy and Velocity

Q4 Which of the following is incorrect?

  • (a) A scalar quantity is one which is always conserved
  • (b) Polar quantity is that which acts along the axis of rotation
  • (c) Only same nature of vectors can be added
  • (d) Resultant of vectors taken in same order is zero

  • (a) A scalar quantity is one which is always conserved

Q5  The magnitude of a vector is always a scalar.

  • a) True
  • b) False 

  • a) True

Q6 A scalar quantity does not vary from one point to another in space.

  • a) True
  • b) False

  • b) False

Q7  A scalar quantity does not vary from one point to another in space.
