# A particle with a mass of 6.64x10^–27 kg and a charge of+3.20x10^–19 C is accelerated from rest through a potential difference of 2.45x10^6 V.

**1.** A particle with a mass of 6.64x10^–27 kg and a charge of+3.20x10^–19 C is accelerated from rest through a potential difference of 2.45x10^6 V. The particle then enters a uniform1.60-T magnetic field. If the particle’s velocity is perpendicular to the magnetic field at all times, what is the magnitude of the magnetic force exerted on the particle?

**2.** Determine the currents in the resistors for the circuit. E1=25.0 V, E2= 6.0 V, E3= 6.0V, Ra= 6.0 ohms, Rb= 3.0 ohms, Rc= 5.0ohms, Rd= 10.0 ohms, Re= 6.0 ohms
