Chapter 2 Vectors and Equilibrium MCQs

Multiple choice questions or MCQs are order of the day. Any student taking a test and getting more than 90% marks will surely get similar marks in board exam. The resultant vector is changed it order of vectors is changed? If a vector is lying along y-axis than its x-component is equal to zero? The dot product of two non zero vectors which are at right angle to each after is always equal to zero? If the body is at rest or rotating with uniform angular velocity the angular acceleration will be zero?
