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?

Two forces act together on an object? The magnitude of their resultant is least when angle between them is? Two lines …………? to each other are known as co-ordinate axes? When a vector is multiplied by –1, the direction changes by …………? The signs of x and y components of resultant vector determine the ………? in which the resultant vector lies? The dot product of two vectors A and B in terms of rectangular components is ……………

When the line of action of an applied force passes through pivot point then the value of moment arm is ……………? The body will be in translational equilibrium when there is no ……………A body of mass “m” is moving in the downward direction to an inclined plane making an angle q to the horizontal? Find the magnitude of the resultant force? Write down the names of two examples of scalar product? Can a body ratate about its centre of gravity under the action of its weight? Give reason?
