### JEE Main 2024  Physics and Measurement: Important Questions vs Formulas

JEE Main formulas are like the building blocks of success in the exam, and when combined with well-structured Physics and Measurement Important Questions for JEE Main, they become an indispensable tool for comprehensive understanding. As you solve your Important Questions in Physics and Measurement for JEE Main, incorporate the associated formulas. Understand how the formula can be used while solving the Important Questions.

## Most Important Formulas of Physics and Measurement

1. Absolute Error for $\mathbf{n t h}$ reading $=\Delta a_n=a_n-a_m=$ true value - measured value

2. Mean Absolute Error $=\Delta \bar{a}=\frac{\left|\Delta a_1\right|+\left|\Delta a_2\right|+\ldots\left|\Delta a_n\right|}{n}$

3. Relative Error $=$

Relative error $=\frac{\Delta a}{a_m}$

4. Percentage Error $=\frac{\Delta a}{a_m} \times 100 \%$

5. Absolute Error in Sum $(\mathrm{x}=\mathrm{a}+\mathrm{b})=\Delta x= \pm(\Delta a+\Delta b)$

6. Absolute Error in Difference $(\mathrm{x}=\mathrm{a}-\mathrm{b})=\Delta x= \pm(\Delta a+\Delta b)$

7. Relative Error in Product $(\mathrm{x}=\mathrm{a} . \mathrm{b})=\frac{\Delta x}{x}= \pm\left(\frac{\Delta a}{a}+\frac{\Delta b}{b}\right)$

8. Relative Error in Division $(\mathrm{x}=\mathrm{a} / \mathrm{b})=\frac{\Delta x}{x}= \pm\left(\frac{\Delta a}{a}+\frac{\Delta b}{b}\right)$
