Question

Section 1robllem PreviousS Problem List Next (1 point) Each vector field shown shown represents the force on a particle at different points in the plane as a result of another particle at the origin. Match each vector field with its description ? 1. A repulsive force whose magnitude decreases as distance increases ? 2. A repulsive force whose magnitude increases as distance increases ? 3. An attractive force whose magnitude increases as distance increases ? 4. An attractive force whose magnitude decreases as distance increases (Click on a graph to enlarge it.) Note: You can earn 50% partial credit for 2-3 correct answers

Explanation / Answer

We need to consider two parameters :

1.If the direction of vector field is away from the then force is repulsive, else it is attractive.

2. Length of arrow denotes strength of force at a point.

So, considering these two points , answer are

1.B

2. C

3. D

4.A
