Two forces F1=10N of E and F2=5N, 37S of W act at apoint. Determine the magnitude and direction of resultant force.​

Which statement is true about an object that is moving in a circular motion due to centripetal force, f, when the radius of its circular motion is doubled? the new force then becomes equal to 2f the new force then becomes equal to f the new force then becomes equal to f/2 the new force then becomes equal to f2 the new force then becomes equal to 1/f
