Question

Two strong permanent magnets are placed one inch apart. which two fundamental forces will most affect them.

Weak and gravity
Strong and electromagnetic
Gravity and strong
Electromagnetic and gravity
An object is transported from Earth to deep space, far from any stars or planets. What happens to the mass and weight of the object?
Both the weight and mass of the object change.
Neither the weight nor the mass of the object change.
The weight of the object changes, the mass stays the same
The mass of the object changes, the weight stays the same

Answer 1

When two permanent magnets are placed adjacent to each other then they will exert magnetic force on each other.

There are four fundamental forces in nature

1. Gravitational force

2. Electromagnetic force

3. Weak Nuclear force

4. Strong nuclear force

So here magnets will exert two fundamental forces on each other Electromagnetic force and Gravity

#2

mass is defined as the composition or amount of substance while we can define weight as gravitational force of earth of the given object

Now when we transport an object from surface of earth to space far away from any planet then the amount of substance or mass will not change while the weight of the substance will decrease to zero because there is no gravity at this position

So we can say

mass = constant and will remain same

Weight = mass * gravity = 0

The weight of the object changes, the mass stays the same
