A negatively charged particle of mass m= 1.17x10-24 kg and q = -3.20x10-19 C is immersed in a uniform 2.00 x 103 N/C electric field pointing in the negative x direction. The particle is initially traveling antiparallel to the uniform electric field at a speed of 2.00x104 m/s. Assume that the gravitational force acting on the particle is negligible compared to the electrostatic force acting on it. Consider a period of time during which the particle travels a distance of 100 mm antiparallel to the uniform electric field.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
