A neutral is simply one which contains and equal number of positive and negative charges.
So when a charged object interacts with the neutral object, it attracts the opposite charge to the side of the interaction and repels the same charge to the opposing side of the interaction.

Answer:

an attractive force

a noncontact force

a vertical force

Explanation:

Gravitational force is a NON-CONTACT FORCE. Gravitational force acts on all bodies on the earth that have mass. The force which is exerted through weight acts on the center of gravity of the body. The force is directed towards the center of the earth. The weight of a body is the gravitational force exerted by the earth on the body.

**Answer:**

B 14.5 m/s to the east

**Explanation:**

We can solve this problem by using the law of conservation of momentum.

In fact, if the system is isolated, the total momentum of the system must be conserved.

Here the total momentum before the stuntman reaches the skateboard is:

where

M = 72.0 kg is the mass of the stuntman

v = 15.0 m/s is his initial velocity (to the east)

The total momentum after the stuntmen reaches the skateboard is:

where

m = 2.50 kg is the mass of the skateboard

v' is the final velocity of the stuntman and the skateboard

Since momentum must be conserved, we have

And solvign for v',

And since the sign is the same as v, the direction is the same (to the east).
