An object weighs 100 N.If the gravitational constant G were half of what it is currently,what would the weight of the object be?
A)100 N
B)50 N
C)25 N
D)200 N

Question

Quizplus · Accepted Answer

Weight is calculated by multiplying the mass of the object by gravitational acceleration g, which depends on the value of G. So, if G is decreased to half, the value of g will also decrease to half. Therefore, the weight of the object will be half of its original weight (100 N/2 = 50 N).
