No force contributes to density, the density is a physical quantity that is defined as being 
the raport between the mass of the object and its volume. However if you want to measure the density of an object you might want to determine its gravity force (weight) 
from which knowing the gravitational acceleratin you can find its mass

(1) <span>Electric current is defined as the rate of </span>charge<span> flow past a given point in an electric circuit. It is measured in Coulombs/second, also called Amperes. In </span>DC electric circuits<span>, it can be assumed that the </span>resistance<span> to current flow is a constant so that the current in the circuit is related to </span>voltage<span> and resistance by </span>Ohm's law, which is:

V = I*R
Where V = Voltage
I = Current
R = Resistance

(4) <span>Renewable energy is the energy which is generated from the natural sources i.e. sun, tides, wind etc. Examples are: Solar Energy, Wind energy( windmill) etc. for electricity generation.
Advantages of Renewable Energy:
1) It is available in abundant quantity.

Disadvantages of Renewable Energy:
1) It is not easy to setup plants and machinery for renewable energy.
2) Initial costs for setting up those plants and machinery is quite high.
3) The energy from the natural sources is not available 24/7. In Solar energy case, energy </span><span>can be used during the day time and not during night or rainy season etc.

Answer:
Explanation:
Deflection in the drop is due to electric field force
so we will have
acceleration of the drop is given as
now we know that time to cross the plates is given as
now the deflection is given as
