Plot a graph showing the variation of electric field as a function of r>R and r
Gravitation Gravitation is the attraction between objects that have mass. Newton's law states: The gravitational attraction force between two point masses is directly proportional to the product of their masses and inversely proportional to the square of their separation distance.

You can find the gradient of $1/r$ more easily using the chain rule and the identity $\nabla r^2 = 2 \vec r$. In particular, $$\nabla \frac{1}{r} = \nabla \frac{1}{\sqrt{r^2}} =- \frac{1}{2 (r^2)^{3/2}} \nabla r^2 =-\frac{\vec r}{ r^3} = -\frac{\hat r}{r^2}$$ Finally, in evaluating the problem $\nabla \cdot \hat r$, you can use the product rule:

The " coefficient of determination " or " R-squared value ," denoted R 2, is the regression sum of squares divided by the total sum of squares. Alternatively (as demonstrated in the video below), since SSTO = SSR + SSE, the quantity R 2 also equals one minus the ratio of the error sum of squares to the total sum of squares:

The coefficient of determination or R squared method is the proportion of the variance in the dependent variable that is predicted from the independent variable. It indicates the level of variation in the given data set. The coefficient of determination is the square of the correlation (r), thus it ranges from 0 to 1.

Here are some basic characteristics of the measure: Since r 2 is a proportion, it is always a number between 0 and 1.; If r 2 = 1, all of the data points fall perfectly on the regression line. The predictor x accounts for all of the variation in y!; If r 2 = 0, the estimated regression line is perfectly horizontal. The predictor x accounts for none of the variation in y!

(y1-y_bar)^2 + (y2-y_bar)^2 + (y3-y_bar)^2 = (1-2)^2 + (2-2)^2 + (3-2)^2 = 2. this is going to be a very small fraction over here. 1 minus a very small fraction is going to be a number close to 1. So then, our R-squared will be close to 1, which tells us that a lot of the variation in y is described by the variation in x. Which makes sense.
