The resultant of the forces and is . If is double then the resultant also doubles in magnitude. Find the angle between and .
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 particle is moving westward with a velocity Its velocity changed to northward. The change in velocity vector is:
(A) towards north east
(B) towards north west
(D) towards north west
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)
