To check the correctness of the formula \( f = \frac{mv^2}{r^2} \) using dimensional analysis, we will follow these steps: ### Step 1: Identify the dimensions of force The left-hand side of the equation is force \( f \). The dimensional formula for force is given by: \[ \text{Force} = \text{mass} \times \text{acceleration} \] The dimensional formula for mass is \( [M] \) and for acceleration (which is \( \frac{\text{velocity}}{\text{time}^2} \)) is \( [L][T^{-2}] \). Therefore, the dimensional formula for force is: ...
