Find the total charge on a circular disk defined by r ≤ a and z = 0 if:a)rhos= rhoso cos(φ) (C/m2) b)rhos= rhoso sin2(φ) (C/m2) c)rhos= rhoso e−r (C/m2) d)rhos= rhoso e−r sin2(φ) (C/m2) where rhoso is a constant.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
