Aspacecraft is launched from earth toward the moon where will the spacecraft be when the gravitational forces acting on it are equal

a closer to earth than to the moon because the moon has greater mass than the earth

b closer to the moon because the moon greater mass than the earth

c closer to earth than to the moon because earth has greater mass

d closer to moon than earth because earth has a greater mass than the moon

D Closer to moon than earth because earth has a greater mass than the moon

Explanation:

As we know that gravitational force is given by

so here if the net gravitational force at some distance between moon and earth is zero or equal due to moon and earth then in that case

so here we can say

so here we will have

since mass of earth is more than mass of moon so we can say

so here we have

so the position is closer to moon because moon is of smaller mass than earth

does anyone know or what?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
