Question

an ant travels a distance of 8cm from p to q and then moves a distance of 6cm at right angles to p and q find its resultant displacement

Answer 1

distance from p to q=8 cm
and after making an angle 90 with p and q it travels =6 cm
so,using phythagoras theorem
d(displacement)=$\sqrt6*6+8*8}$
d=10 cm
