Answer 1

Answer #1

The oceanic ridge is the most extensive chain of mountains on Earth, stretching nearly 65,000 kilometers (40,390 miles) and with more than 90 percent of the mountain range lying in the deep ocean.
Oceanic ridges are found in every ocean basin and appear to girdle Earth. The ridges rise from depths near 5 km (3 miles) to an essentially uniform depth of about 2.6 km (1.6 miles) and are roughly symmetrical in cross section. They can be thousands of kilometres wide.

Under normal atmospheric conditions, there exists a weak electric field near the earths surface, pointing vertically downward, whose value is 150 N/C. Find the necessary charge on a 2.70 gram ping-pong ball so that the ball could "levitate' in this field. In other words, the upward electrical force would just balance the downward gravitational force. Would the acquired charge need to be positive or negative?
