1. A proton has an initial speed of 5.0×105 m/s .
a.) What potential difference is required to bring the proton to rest? (in V)
b.)What potential difference is required to reduce the initial speed of the proton by a factor of 2?
c.)What potential difference is required to reduce the initial kinetic energy of the proton by a factor of 2?
♦ Relevant knowledge
Potential difference is defined as the amount that can be determined by the voltmeter device by connecting it in the form of a parallel arrangement. Furthermore, the potential difference is a key understanding of electrical circuits.
