## Centre of gravity and centroid

1. The Centre of Gravity can be defined as a point on an object where its whole weight is focused on. In simple words, the gravitational pull is said to act at the same exact point of that object. Whereas, a Centroid is a point which is considered to be the geometrical center of an object. [adinserterRead more

The Centre of Gravity can be defined as a point on an object where its whole weight is focused on. In simple words, the gravitational pull is said to act at the same exact point of that object. Whereas, a Centroid is a point which is considered to be the geometrical center of an object.

### Difference between the Centre of Gravity and Centroid

Difference 1: Center of Gravity is represented by g whereas the Centroid is denoted by c.

Difference 2: The Center of Gravity equals the average of all the points in a uniform gravitational field whereas the Centroid is a point with no moment of area in a plane area.

Difference 3: Center of Gravity of an object can be derived by finding out the intersection of all the gravitational lines. On the other hand, a Centroid can be derived by finding out the average position of all the geometrical points of an object.

Difference 4: The Center of Gravity can be calculated by taking the sum of all the moments of an object divided by that object’s weight. On the other hand, there are several methods to determine the centroid of an object. For example, the centroid of a triangle can be determined by finding out the point of intersection of all the three medians.

Pursuing a doctoral level in Law is a choice of many who have a great interest in the field of research. Moreover, a PhD in Law could bring you the reputed status that you cherish for than just being a one among the thousands. So, let’s discuss the process involved in pursuing a Ph.D. in Law.

### Eligibility to pursue PhD in Law

The first thing to note is the eligibility required to pursue a doctoral degree in Law –

1. You should hold an LLM Degree from a recognized university.
2. The minimum marks secured should be not less than 55%.
3. A few reputed universities like IGNOU require a minimum teaching experience of 5 years.

### PhD entrance test

Besides having eligibility, you will have to take the Ph.D. entrance exam conducted by the university that you apply for. In India, there are some reputed universities like IGNOU (Indira Gandhi National Open University), NLU Jodhpur (National Law University), NALSAR (National Academy of Legal Studies and Research, Hyderabad), NLS Bengaluru, etc.

These universities conduct their own Ph.D. entrance tests and will have their own eligibility criteria. So, it’s better to go through the application process of the university from which you want to get a doctoral degree.

For example, IGNOU requires you to submit the Research Proposal prior to taking the entrance test. So, besides having the required aggregate marks of 55% in LLM, you should also submit a research proposal in order to pursue PhD from IGNOU.

At the same time, a few universities may not require you to take the admission test if you have already got qualified for some national level exams like UGC NET/JRF, SLET, and M.Phil.
