Positive charge is distributed along the entire x axis with a uniform density 12 nc/m. a proton is placed at a position of 1.00 cm away from the line of charge and released from rest. what kinetic energy in ev will it have when it reaches a position of 5.0 cm away from the initial position? (note: use the potential difference equation for an infinite line.) a. 350 ev b. 390 ev c. 350k ev d. 6.2 ev e. 170 e

Which statement correctly describes the current in a circuit that is made up of any two resistors connected in parallel with a battery? a. the current in the battery and in each resistor is the same b. the current the battery equals to the sum of the currents in the resistors c.the current in the battery is less than the current in either resistor d. the current in the battery equals to the product of the currents in the resistors

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
