Question

Scientist are working on a new technique to kill cancer cells zapping them with ultrahigh Light that for an extremely short time (a few nanoseconds ). These short pulses scramble as long pulses as would do 4.4.in diameter with the pulses lasting for 5.0 We an average that The energy is spread uniformly over the faces of 100 cells for each pulse How much energy is given to the cell during this pulse? Express your answer using two significant What is the intensity (in w/m2) delivered to the cell Express your answer Two Significant figures . What is the maximum value of the electric field in the pulse Express your answer using two significant What is the maximum value of the magnetic field in the pulse Express Your answer using two significant

Explanation / Answer

part 1) 2.17*10^12W * 5.0*10^-9 s= 10850J/100cells= 108.5 J

part 2) I=W/m^2; I=2.17*10^12 / {(2.2*10^-6)^2*pi}= 1.42 x 10^23

part 3)

E = SQRT (2 I / c EPSILON)

= sqrt [ ( 2 x 1.42 x 10^23 )/(3 x 10^8 x 8.85 x 10^-12)]

= 1.03 x 10^13 V/m

part d) B = E/c = 1.03 x 10^13/3 x 10^8 = 34333.33 T
