The electric field everywhere on the surface of a thin, spherical shell of radius 0.750 m is of magnitude 890 n/c and points radially toward the center of the sphere. (a) what is the net charge in nano coulomb within the sphere’s surface? (b) what can you conclude about the nature and distribution of the charge inside the spherical shell?

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?
