Answer:
98N
Step-by-step explanation:
Given parameters: 
Mass of the bowling ball = 10kg 
Mass of the softball = 1kg 
Unknown: 
Force of gravity on the bowling ball = ? 
Solution: 
The force of gravity on an object is the same as the weight of the body; 
 Weight = m x g 
m is the mass 
g is the acceleration due to gravity = 9.8m/s² 
 Weight of bowling ball = 10kg x 9.8m/s² = 98N
