Two forces, one of 3 newton and another of 4 newton are applied on a standard 1 kg body, placed on a horizontal and frictionless surface, simultaneously along the x -axis and the y-axis, respectively, as shown below: The magnitude of the resultant acceleration is:
Options
- A7 ~m / s ^2
- B1 ~m / s ^2
- C5 ~m / s ^2
- D7 ~m / s ^2
Correct answer
C. 5 ~m / s ^2
Step-by-step solution
Final force will be along the Z axis. F= (3)^2+(4)^2 aligned & = 9+16= 25=5 & Acceleration (a)=F / m=5 / 1=5 ~m / s ^2 aligned
