Question

What is the net force of a 4.0 N force and an 9.0 N forceacting on an object for each of the following conditions? a) The forces act in opposite directions.____________N b) The forces act in the same directions.____________N How would the force of gravity between two masses, be affectedif the sepration distance between them were the following. a) tripled F2/F1 = ___________ b) decreeased by one-third F2/F1= ____________ What is the net force of a 4.0 N force and an 9.0 N forceacting on an object for each of the following conditions? a) The forces act in opposite directions.____________N b) The forces act in the same directions.____________N How would the force of gravity between two masses, be affectedif the sepration distance between them were the following. a) tripled F2/F1 = ___________ b) decreeased by one-third F2/F1= ____________

Explanation / Answer

a) let the direction of the 9.0N is positive, the net force is F = 9.0N - 4.0N = 5.0N answer: 5.0N b) net force F = 9.0N+5.0N = 14.0N c) F1 = Gm1*m2/r2 now r -> 3r F2 = Gm1*m2/(3r)2 = F1/9 =>F2/F1 = 1/9 d) now r ->r/3, we have: F2 = Gm1*m2/(r/3)2 = 9F1 =>F2/F1 = 9 now r -> 3r F2 = Gm1*m2/(3r)2 = F1/9 =>F2/F1 = 1/9 d) now r ->r/3, we have: F2 = Gm1*m2/(r/3)2 = 9F1 =>F2/F1 = 9
