Question
I keep receiving the same answers for the last two parts of this problem and I cannot for the life of me figure out what I've miscalculated! Please help!
A proton is released from rest in a uniform electric field of magnitude 382 N/C. (a) Find the electric force on the proton magnitude 6.11e-17 N in the direction of the electric field (b) Find the acceleration of the proton magnitude Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Ca direction in the direction of the electric field 3.82e10 out all intermediate results to at least four-digit accuracy to minimize roundoff error. m/s2 (c) Find the distance it travels in 2.12 8.58e22 Your response is within 10% o the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Car four-digit accuracy to minimize roundoff error. cm out all intermediate results to at leastExplanation / Answer
electric field E = 382 N/C
proton charge q = 1.6 * 10^-19 C
mass of proton m = 1.67 * 10^-27 kg
a) electric force F = q * E
F = 1.6 * 10^-19 * 382
F = 6.11 * 10^-17 N
direction is in the direction of electric field
b)
acceleration a = F / m
a = 6.11 * 10^-17 / (1.67 * 10^-27)
a = 3.6586 * 10^10 m/s^2---------------------------------------------------Answer
direction is in the direction of electric field
c)
to calculate distance we use
S = (u*t) + (1/2 * a * t^2)
S = (0) + (1/2 * 3.6586 * 10^10 * (2.12 * 10^-6)^2)
S = 82 mm----------------------------------Answer
