Gravitation : What is the formula for the universal law of gravitation? : Class 11 Physics

Here we discuss the Gravitational Force due to the Solid Sphere of Chapter 17 Gravitation of Class 11 Physics.

A typical gravitation class 11 syllabus will include certain mathematical problems related to the force of gravity and there are some basic concepts that one needs to be aware of.
For that, all that one needs to do is understand the premises of the universal law of gravitation and how it can be applied.

What is Gravitation?
Every object in the universe attracts every other object with a force which is called the force of gravitation.
The gravitational force is the force of mutual attraction between any two objects by virtue of their masses. It is a universal force. Every object experience this force due to every other object in the universe.

All objects on the earth, for example, experience the force of gravity due to the earth.
We will discuss the scenario where the test point is outside as well as inside of the shell.
For an external test point, solid sphere behaves like a point mass placed at the center of the sphere.
Here we will also use a few examples to find the gravitational force due to the solid sphere.
We can understand it by taking some examples as in our video.

All the above-mentioned topics are described in an interactive and efficient manner so that the students could easily understand them.

The chain rule states that the derivative of f(g(x)) is f'(g(x))_g'(x). In other words, it helps us differentiate *composite functions*. For example, sin(x_) is a composite function because it can be constructed as f(g(x)) for f(x)=sin(x) and g(x)=x_. Using the chain rule and the derivatives of sin(x) and x_, we can then find the derivative…

Amazing, Life Changing Tutor
Before I met Jonathan, I was struggling through most of my STEM classes because I was simply not studying properly. He taught me all kinds of new study habits that would help me to save time, raise my grades, and lower my stress. Jonathan was specifically tutoring me in vector calculus and is an amazing tutor on the subject. You will walk away from a lesson with a game plan knowing exactly what you need to do before your next session with him or before your next exam in order to do well in the course. I highly recommend him as a tutor.
