Apoint charge q1 = -2.3 μc is located at the origin of a co-ordinate system. another point charge q2 = 6.2 μc is located along the x-axis at a distance x2 = 9.9 cm from q1. 1) what is f12,x, the value of the x-component of the force that q1 exerts on q2?

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
