The diagram shows the electric field around a point charge. The electric field points radially outward from the point. The magnitude of the electric field
A)
Decreases linearly as you move out from the charge.
B)
Increases linearly as you move out from the charge.
C)
Decreases proportional to the square on the distance from the charge.
D)
Increases proportional to the square on the distance from the charge.

A

Explanation:

Usatp got it correct

The trucks must have equal masses that is they must have same load.

Explanation:

Momentum refers to the product of the mass of the object and velocity.

As momentum has both magnitude and direction, it is a vector quantity.

In the given problem, it is given that after the collision, the trucks move at more than half the original speed of the moving truck. Therefore, the trucks must have equal masses that is they must have the same load.
