Two objects, x and y, move toward one another and eventually collide. object x has a mass of 2m and is moving at a speed of 2v0 to the right before the collision. object y has a mass of m and is moving at a speed of v0 to the left before the collision. which of the following describes the magnitude of the forces f the objects exert on each other when they collide? a. the force exerted by x on y is 4f to the right, and the force exerted by y on x is f to the left. b. the force exerted by x on y is 2f to the right, and the force exerted by y on x is f to the left. c. the force exerted by x on y is f to the right, and the force exerted by yon x is f to the left. d. the force exerted by x on y is f to the left, and the force exerted by y on x is f to the right.

The force exerted by object X on Y is 4F to the right and the force exerted by object Y on X is F to the left.

The given parameters;

The force exerted by the object Y is calculated as follows;

where;

t is the time of impact

The force exerted by object X on Y is 4F to the right. And the force exerted by object Y on X is F to the left. Hence, option (a) is correct.

Given data:

The mass of object X is, 2M.

The initial velocity of X is, .

The mass of object Y is, M.

The initial velocity of Y is, .

Applying the concept of impulse-momentum to obtain average force by object X as,

............................................................(1)

Here, t is the reaction time.

Similarly,  average force by the object Y is,

...................................................................(2)

Taking ratio of equation (1) and (2) as,

Thus, we can conclude that the force exerted by object X on Y is 4F to the right. And the force exerted by object Y on X is F to the left. Hence, option (a) is correct.

c) up is the direction the magnetic force is acting on the charge.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
