A shopper walks westward 2.8 meters and then eastward 9.2 meters. What is the magnitude and direction of the displacement?

6.4 meters eastward

Explanation: you’re displacement is supposed to be the distance of the initial position to the final position (where you started to where you finished) so that means you would have to subtract 9.2 by 2.8 to get 6.4, and because you subtracted from 9.2 the direction is eastward.

Hope I helped!

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
