Question

To measure the radius of curvature with a spherometer, we use the formula

• A. R = $\frac{h^{2}}{6}$ + $\frac{1}{\mathcal{l}}$
• B. R = $\frac{\mathcal{l}^{2}}{6h}$ + $\frac{h}{2}$
• C. R = $\frac{h^{2}}{2\mathcal{l}}$ + $\frac{1}{h}$
• D. R = $\frac{2\mathcal{l}^{2}}{h}$ + $\frac{6}{\mathcal{l}}$

Answer 1

Answer: (B)

R = $\frac{\mathcal{l}^{2}}{6h}$ + $\frac{h}{2}$

Answer 2

$R = \frac{\mathcal{l}^{2}}{6h} + \frac{h}{2}$; M⁰ L¹ T⁰
