A child's toy arrow has a suction cup on one end. When the arrow moving in positive x direction hits the wall, it sticks. The radius of the suction cup is 1.0 cm. Suppose that the mass of the arrow is about 10 g and it is concentrated in the suction cup. Assume that a vacuum exists between the suction cup and the wall. The atmospheric pressure is 1.0×105N/m2.

Determine the magnitude of the gravitational force exerted by Earth on the suction cup.
