Light of wavelength 1 and 2 pass through Young's double-slit apparatus. The 4th dark band from 1 occurs at the same angle as the 5th bright band (not including the central maximum) of 2. What is the ratio of 2 to 1? Is gravitational force affected by angle?
Gravitational force: It is the force that is exerted by the Earth on every object, which is near or on its surface. For example, an apple falling from a tree branch towards the ground is due to gravitational force.What is gravitational force in Short answer? part 2...

We define in physics the four fundamental forces which are the weak force, strong force, electromagnetic force, and the gravitational force. The gravitational force is the force of attraction between all masses on earth. This means that any objects are attracting each other because of the ...
A. Gravitational force. B. Buoyant force. C. Magnetic force. D. Frictional force. 相关知识点: 试题来源: 解析 B。解析:文章中提到“When an object is placed in water, it experiences an upward force called buoyant force. If the buoyant force is greater than the weight of the object, the...
Mathematically, gravitational force can be represented as: F=Gm1m2r2 Here, F is the gravitational force. G is the universal gravitational constant. m1is the first body's mass. m2is the second body's mass. r is the distance between the two bodies. ...
Which planet has the strongest gravitational force? Jupiteris the largest in our Solar System, meaning it also has the highest gravity. You would weigh two and a half times on Jupiter than what you would on Earth. Gravity is a fundamental force of physics, which keeps everything attracted to...
on or near the surface of the Earth, the gravitational force equals your weight. On a different astronomical body like Venus or the Moon, the acceleration of gravity is different than on Earth, so if you were to stand on a scale, it would show you that you weigh a different amount than...
