A vector  is directed along 30° west of north direction and another vector  along 15° south of east. Their resultant cannot be in ____________ direction.

ABCD is a quadrilateral. Forces  act at a point. Their resultant is 

The maximum and minimum magnitude of the resultant of two vectors are 17 units and 7 units respectively. Then the magnitude of resultant of the vectors when they act perpendicular to each other is:

A vector  makes an angle of 20° and  makes an angle of 110° with the X-axis. The magnitudes of these vectors are 3 m and 4 m respectively. Find the magnitude of the resultant.

Consider east as positive x-axis, north as positive y-axis and vertically upward direction as z-axis. A helicopter first rises up to an altitude of 100 m than flies straight in north 500 m and then suddenly takes a turn towards east and travels 1000 m east. What is position vector of helicopter. (Take starting point as origin)

A force  Newton produces acceleration 1 m/s² in a body. The mass of the body is (in kg)

The vector having a magnitude of 10 and perpendicular to the vector is
