A circular disc is rotating about an axis through its circumference in a vertical plane. If its mass is 0.1 kg and radius 0.5 m, its M.I. In kg. $m^2$ units about this axis will be a. 0.0375 b. 0.025 c. 0.5 d. 0.75

Sure, I can do that. Here's an example of step by step solutions using LaTeX tags: Problem: Solve for x: $4x-2=10$ Solution: Step 1: Add 2 to both sides of the equation to isolate the variable. $\begin{array}{rl}4x-2+2& =10+2\\ 4x& =12\end{array}$ Step 2: Divide both sides of the equation by 4 to solve for x. $\begin{array}{rl}\frac{4x}{4}& =\frac{12}{4}\\ x& =3\end{array}$ Step 3: Check your answer by plugging it back into the original equation. $\begin{array}{rl}4(3)-2& =10\\ 12-2& =10\\ 10& =10\end{array}$ Since both sides of the equation are equal, the solution is correct. Therefore, $x=3$.
