Mass does not change anywhere in the space .
So the given 30N is equal to the product of mass of the body and the acceleration due to gravity at that place in space.
After finding the mass of the body multiply it by the given acceleration due to gravity.
Mg is the approximate force due to gravity between the mass and the planet.
I hope this may help you.
Answer:
Magnetic field lines can be drawn by moving a small compass from point to point around a magnet. At each point, draw a short line in the direction of the compass needle. Joining the points together reveals the path of the magnetic field lines.
Explanation:
Answer:
D. 1/16 It's weight on the surface.
Explanation:
As we know that the gravity due to earth at its surface is given as

now at the distance of 4 radius of earth the gravity is given as

so we can say that

so here gravity becomes 1/16 times of the gravity due to earth on its surface
now we know that weight on the surface of earth is given as

also the weight now at the given height is given by

so here correct answer will be
D. 1/16 It's weight on the surface.
The answer is C.endothermic change.
