A conductive wire is made up of two segments, one straight and one circular. Each segment is uniformly charged with a charge of +Q as illustrated in the figure. a) Calculate the electric field due to the straight segment at point P that lies at a distance R from the origin, the electric field due to the quarter circle at point P which is at a distance R from the origin and net electric field at point P.
b) If = 9 nC and = 10 cm. What should be the magnitude of a charge located at point P so that it perceives a force of 0.05 N?
c) Is the electric field at the origin stronger or weaker than at P? Why? Qualitatively justify.
d) Find out the limit set by the European Union as
reference for exposure to an electric field and determine which
should be the load value in each segment so that the field
electrical power at P due to both, reach this value. Take R as 1 m.

hi there if you are asking for conformation that wavelingth is the correct answer is wrong it is the answer is frequency. : )

i hope this you out, have a wonderful day

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
