Answer:
option A
Explanation:
given,
distance between two masses is doubled
new distance, r' = 3 r
using gravitational force equation
............(1)
new gravitational force
now from the given condition
now, from equation (1)
now, the change in gravitational force factor is equal to
Hence, the correct answer is option A
The answer for the online test is going to be the last one, D
Jennifer
Explanation:
she has more mass which means she is using more force
The net force will point towards the acceleration of the object, as supported by Newton's second law.
