Draw a net force arrow on the picture below. What is the net force? State the direction.
2 answers:
Answer:
Net force=0 N
Explanation:
The drawing will look like the attached image, with no net force on the object. We stablished a reference system located in the center of the body, with + axis take right and upward for x and y. All forces are on the x axis, there is one positive force of 7 N (pointing right) and to negative forces of -4 and -3 N (pointing left) if we add the vectors in the x axis we have that
+7-4-3=0 N
The net force is then 0 newton and the drawing has no net force vector then

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
