In the context of precision measurements, the vernier caliper is an instrument that allows for more precise measurements than a standard ruler or measuring tape. …

An electron is moving around an infinite linear charge in a circular path of diameter $\large{0.30 m}$ . If linear charge density is $\large{10^{-6} C/m}$ , then calculate the speed of an electron. ( $\large{m_e= 9.0 \times 10^{-31} kg, e = 1.6 \times 10^{-19} C}$ )
