Weight of clouds?

A piece of cloud is having area 25xx10^(6)m^(2) and electric potential of 10^(5) volts. If the height of cloud is 0.75 km, the energy of electric field between earth and cloud will be

The angle of elevation of a cloud from a point 60m above a leke is 30^(@) and the angle of depression of the reflection of cloud in the alek is 60^(@). Find the height of the cloud.

If the angle of elevation of a cloud from a point P which is 25 m above a lake be 30^(@) and the angle of depression of reflection of the cloud in the lake from P be 60^(@) , then the height of the cloud (in meters) from the surface of the lake is

The angle of elevation of a cloud from a point 60m above a lake is 30o and the angle of depression of the reflection of cloud in the lake is 60_(0). Find the height of the cloud.

The angle of elevation of cloud from a point 60 m above a lake is 30^(@) and the angle of depression of the reflection of cloud in the lake is 60^(@) . Find the height of the cloud .

Normally, the upper layers of clouds get charged and the layers of clouds near the earth get--charged.
