Heavenly body. 19. The mass of Jupiter is 1.910 kg and its radius is 71 x 10 m. Find the gravitational
field intensity at its surface and at a distance of 142 10 m. What is the weight of
the body of mass 80 kg at its surface?
Ans: 25.14 N/ke, 2011 2

Electric charge is uniformly distributed inside a nonconducting sphere of radius 0.30 m. the electric field at a point p, which is 0.50 m from the center of the sphere, is 15,000 n/c and is directed radially outward. what is the maximum magnitude of the electric field due to this sphere

What are atoms of the same element with varying number of neutrons

Apulley with mass mp and a radius rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.
