Answer:
The magnitude of charge on the particle is .
Explanation:
Given that,
The magnitude of electric field, E = 215 N/C
The electrical potential energy of the charge decreases by, as it moves.
We need to find the magnitude of the charge on the moving particle. The change in electric potential energy is given by :
.........(1)
The electric potential in terms of electric field is given by :
Equation (1) becomes :
So, the magnitude of charge on the particle is .
Answer:
it increases the surface tension of the water
