Two thin 80.0-cm rods are oriented at right angles to each other.Each rod has one end at the origin of the coordinates,and one of them extends along the +x-axis while the other extends along the +y-axis.The rod along the +x-axis carries a charge of -15.0 µC distributed uniformly along its length,and the other rod carries +15.0 µC uniformly over its length.Find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm,40.0 cm).(e = 1.60 × 10-19 C,ε0 = 8.85 × 10-12 C2/N ∙ m2)
P-value
A statistical measure that helps determine the significance of results obtained in hypothesis testing, indicating the probability of observing the obtained results if the null hypothesis were true.
Friedman Test
A test that doesn't rely on parameter-specific data, used to identify treatment variances across several trials.
One-tail
A type of hypothesis test that determines the significance of one end, or tail, of the data distribution.
Two-tail
Pertains to hypothesis tests that consider extreme outcomes in both tails of the distribution, allowing for tests of deviation in two opposite directions.
