Group of physics students are asked to demonstrate Ohm’s Law in parallel circuits. Using their knowledge of Ohm’s Law and the r
ules governing voltage, current, and resistance in series and parallel circuits they must set up an investigation using batteries, wires, three light bulbs of unknown resistance, a voltmeter, and an ammeter. Their task is to determine the resistance of each bulb. Given the equipment at hand, the groups determine that they will collect data to determine the voltage and current at each element in the circuit and use those values to calculate resistance. Four students offered their suggestions on which measurements must be taken to determine the resistance provided by each bulb. Which student’s suggestion below would provide enough evidence to be able to determine the value of each resistor?

Answer:
The magnitude of the electric field be 171.76 N/C so that the electron misses the plate.
Explanation:
As data is incomplete here, so by seeing the complete question from the search the data is
vx_0=1.1 x 10^6
ax=0 As acceleration is zero in the horizontal axis so
Equation of motion in horizontal direction is given as
Now for the vertical distance
vy_o=0
than the equation of motion becomes
Now using this acceleration the value of electric field is calculated as
Here a is calculated above, m is the mass of electron while q is the charge of electron, substituting values in the equation
So the magnitude of the electric field be 171.76 N/C so that the electron misses the plate.
