The magnitude and direction of the acceleration produced in a body of mass 5 kg when two mutually perpendicular forces 8 N and 6 N act on it, are respectively:
A
2 $ms^{-2}$; $\tan^{-1}(3/4)$ with 6 N force
B
2 $ms^{-2}$; $\tan^{-1}(4/3)$ with 8 N force
C
2 $ms^{-2}$; $\tan^{-1}(3/4)$ with 8 N force
D
20 $ms^{-2}$; $\tan^{-1}(4/3)$ with 8 N force
