Often times during volcano eruptions the clouds have large static charge buildups that cause lightning to happen. If a rock is ejected by the volcano and it flies to a height of 1975 m, and the clouds have a charge concentration of +40.0 C at a height of 3500 m and -40.0 C at a height of 1000 m, what is the electric field at the ejected rock? magnitude direction -Select-v N/C Often times during volcano eruptions the clouds have large static charge buildups that cause lightning to happen.
