Which of the following sets of forces acting on an object will result in the object moving?
5 newtons up and 5 newtons down
31 newtons left and 32 newtons right
0 newtons up and 0 newtons down
9 newtons left and 9 newtons right

31 Newtons Left and 32 Newtons Right

Explanation:

If two forces are applied to an object in opposite direction, it will be moved only if the set of forces are not in equilibrium.

Forces going in opposite direction with the same strength are in equilibrium, like first, third and fourth options.

But, if the forces go in opposite direction with different strength, they are not  in equilibrium, like in the second option. In this case, there is a net force going to the right, equal to 32 -31 = 1 Newton.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
