Two forces, one of 3 N and another of 4 N 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;

• A. 7 m/s2
• B. 1 m/s2
• C. 5 m/s2
• D. √7 m/s2
