Two plates of area 7.00 × 10-3 m2 are separated by a distance of 2.60 × 10-4 m. If a charge of 5.40 × 10-8 C is moved from one p

late to the other, calculate the potential difference (voltage) between the two plates. Assume that the separation distance is small in comparison to the diameter of the plates.

Answer:

226.53 Volt

Explanation:

A = Area of plates = 7.00×10⁻³ m²

ε₀ = Permittivity of space = 8.854×10⁻¹² F/m

d = Distance between two plates = 2.60×10⁻⁴ m

Q = Charge = 5.40×10⁻⁸ C

Capacitance

C=\frac{\epsilon_0A}{d}\\\Rightarrow C=\frac{8.854\times 10^{-12}\times 7\times 10^{-3}}{2.6\times 10^{-4}}\\\Rightarrow C=23.83\times 10^{-11}

Potential difference between plates

V=\frac{Q}{C}\\\Rightarrow V=\frac{5.4\times 10^{-8}}{23.83\times 10^{-11}}\\\Rightarrow V=226.53\ Volt

∴ The potential difference (voltage) between the two plates is 226.53 Volt

\large{ \boxed{ \bf{ \color{red}{Universal \: law \: of \: gravitation}}}}

Every object in the universe attracts every other object with a force which is proportional to the product of their masses and inversely proportional to the square of the distance between them. The forces along the line joining the centre of the two objects.

❍ Let us consider two masses m1 and m2 line at a separation distance d. Let the force of attraction between the two objects be F.

According to universal law of gravitation,

\large{ \longrightarrow{ \rm{F \propto m_1 m_2}}}

Also,

\large{ \longrightarrow{ \rm{ F \propto  \dfrac{1}{ {d}^{2} } }}}

Combining both, We will get

\large{ \longrightarrow{ \rm{F  \propto  \dfrac{ m_1 m_2}{ {d}^{2}}}}}

Or, We can write it as,

\large{ \longrightarrow{ \rm{F  \propto  \:  G \dfrac{ m_1 m_2}{ {d}^{2} }}}}

Where, G is the constant of proportionality and it is called 'Universal Gravitational constant'.

☯️ Hence, derived !!

What happens when two forces act in the same direction?
Wewaii [24]

Using the picture provided the forces are added together, because they are putting force on an object the same direction, thus the forces are added.

DNA is coiled into chromosomes in a cell's
tia_tia [17]

Answer: Cell's nucleus

Explanation :

The full form of DNA is Deoxyribonucleic acid. The genetic information of a cell is organized in the DNA. It is inherited from parents by their children.

DNA is coiled into chromosomes in a cell's nucleus. It has a shape like a double helix. It is twisted in the form of spirals.

Hence, DNA is coiled into chromosomes in a cell's Nucleus.
