Since direction is part of velocity, and the object is moving in a circle, its velocity is constantly changing.
To solve this problem we will use the concepts related to the resulting Vector Force product of two components, that is,

If we take the Force of 50 N as the force in the X direction and the Force of 40 N in the Y direction we will have to:



Finally, since Newton's second law, acceleration can be determined as




Therefore the resultant magnitude of the acceleration of the object is 
Therefore as you move around the U.S. the acceleration due to gravity (g) varies from about 9.79 to 9.81 meters per second squared. The Earth’s average is 9.80 m/s2 which is generally reported as the acceleration of gravity on Earth.
Answer:
It is half the field strength at 0.5cm
