Add 100 ML of sulfuric acid to 400 ML of base as an 80H B.
Answer:

Explanation:
The electric force exerted on the electron is given by:

where
is the magnitude of the electron charge
E = 40000 V/m is the electric field
Substituting,

By comparison, the gravitational force exerted on the electron is:

where
is the mass of the electron
g = 9.8 m/s^2 is the acceleration due to gravity
Substituting,

Gravitational potential energy is defined as the amount of energy an object possesses at a given height above the Earth's surface. The equation for gravitational energy is E = mgh. Here, m is the mass of the object, g is the acceleration due to gravity, and h is the height above the Earth's surface. Hence, the answer is E = 2000kg x 9.81m/s^2 x 2m = 39240 Joules.
