The gravitational field strength is approximately equal to 10 N.
<u>Explanation:</u>
Gravitational field strength is the measure of gravitational force acting on any object placed on the surface of the planet. Generally, the mass of the object is considered as 1 kg.
So the gravitational field strength will be equal to the gravitational force acting on the object.
The formula for gravitational field strength is
Here g is the gravitational field strength, m is the mass of the object placed on the surface and F is the gravitational force acting on the object.
Since, the mass of any object placed on the surface of earth will be negligible compared to the mass of Earth, so the mass of the object is considered as 1 kg.
Then the g = F
And
Here G is the gravitational constant, M is the mass of Earth and m is the mass of the object placed on the surface, while r is the radius of the Earth.
So, the gravitational field strength is approximately equal to 10 N.

<h2>Answer</h2>
The force will be doubled.
<h2>Explanation</h2>
Using Newton Law II,
<h3>F = ma </h3>
So it can be seen in the formula that force is directly proportional to mass and acceleration.
if mass is doubled ---> force will be doubled, keeping acceleration constant.
Similarly,
if acceleration is doubled ---? force is will be doubled, keeping mass constant.
<em>It is assumed that there is no friction, the object is in the air with no air resistance.</em>
