Question

What is gravitational field strength ot the center of sphere?

Answer 1

Answer:

the gravitational field strength at a point is the gravitational force exerted per unit mass placed at that point

Answer 2

Answer:

All objects with mass have a gravitational field around them. A gravitational field is where a mass experiences a force.

All matter has a gravitational field that attracts other objects. The more mass an object has, the greater its gravitational field will be. For example, the Earth has a greater gravitational field than the Moon because it has a much greater mass than the Moon. The Moon is attracted to the Earth because it is within the Earth’s gravitational field.
