[Kindly show complete solution with the given and formula used.] A 10-kg box is being pushed up a slippery ramp as shown in the following figure. The coefficient of friction between the box and the ramp is just ? = 0.1. (a) What force does the man need to apply to the box to keep it traveling up the ramp at a steady speed? (b) What fraction of the weight force of the box is this? (c) If the angle of the ramp is raised to 45° then what force does the man need to apply to the box to keep it travelling up the ramp at a steady speed now? (d) What fraction of the weight force of the box is this?
Gravitational force
In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.
Acceleration Due to Gravity
In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.
