06) The electron is imagined to move in a circular orbit about a stationary proton in the Bohr model (we will talk more about the Bohr model later). If the speed of the electron were 6.5x 10 m/s, what would be the corresponding orbital radius? Mass of an electron is 9.11 x 10" kg, and magnitude of charge for an electron and proton is 1.60 x 10 19 C each. Coulomb's constant k is 9.0x 10° N-m2/C2. #7) A 5.0...
