Find Gravitational Force on an object

AI Thread Summary
To find the gravitational force on an object moved to a distance of 4R from the center of a planet, Newton's Law of Universal Gravitation is applied. The gravitational force decreases with the square of the distance from the center of the planet. The weight W of the object at the planet's surface can be used to calculate the new gravitational force at 4R. After some discussion, the correct answer was reached. Understanding the relationship between distance and gravitational force is crucial for solving such problems.

oh thanks i got the answer
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
