A gamma-ray telescope intercepts a pulse of gamma radiation from a magnetar, a kind of star with a spectacularly large magnetic field. The pulse lasts 0.16 s and delivers 9.5 x10^-6 J of energy vertically to the 59-m²surface area of the telescope's detector. The magnetar is thought to be 3.32 x 10²⁰ m (about 35000 light-years) from mearth, and to have a radius of 9.7 x 10³ m. discover the magnitude of the rms magnetic field of the gamma-ray pulse at the surface of the magnetar, assuming that the pulse radiates uniformly outward in all directions. (Suppose a year is 365.25 days.)
