$$f = 20 - 10 = 10$$ N
Using the equation: $$f = \mu N$$, where $\mu$ is the coefficient of friction and $N$ is the normal reaction. m karim physics numerical book solution class 11
The M Karim Physics Numerical Book Solution Class 11 is a valuable resource for students who want to improve their understanding of physics and develop problem-solving skills. By following the solutions and tips provided in this monograph, students can build a strong foundation in physics and excel in their studies. $$f = 20 - 10 = 10$$ N
$$20 - f = 5 \times 2$$
$$20 = 0 + a \times 5$$
$$a = \frac{20}{5} = 4$$ m/s²
$$10 = \mu \times 5 \times 9.8$$
