Answer with Explanation:

We are given that

Distance between two charges,d=2.55\times 10^{-2} m

a_1=4.65\times 10^3 m/s^2

a_2=8.55\times 10^3 m/s^2

Mass of particle 1=m_1=6.05\times 10^{-6} kg

a.We have to find the change on each particle .

Let q_1=q_2=q

Force ,F=\frac{kq_1q_2}{d^2}

Where k=9\times 10^9

Using the formula

F=\frac{9\times 10^9\times q^2}{(2.55\times 10^{-2})^2}

For particle 1

F=m_1a_1

F=6.05\times 10^{-6}\times 4.65\times 10^3=0.028 N

Using the value of F

0.028=\frac{9\times 10^9\times q^2}{(2.55\times 10^{-2})^2}

q^2=\frac{(2.55\times 10^{-2})^2\times 0.028}{9\times 10^9}

q=\sqrt{\frac{(2.55\times 10^{-2})^2\times 0.028}{9\times 10^9}}

q=4.5\times 10^{-8} C

q_1=q_2=4.5\times 10^{-8} C

b.m_2=\frac{F}{a_2}

Using the formula

m_2=\frac{0.028}{8.55\times 10^3}

m_2=3.3\times 10^{-6} kg

Answer:

T = 4.905[N]

Explanation:

In order to solve this problem we must perform a sum of forces on the vertical axis.

∑Fy = 0

We have two forces acting only, the weight of the body down and the tension force T up, as the body does not move we can say that it is system is in static equilibrium, therefore the sum of forces is equal to zero.

T-m*g=0\\T=0.5*9.81\\T=4.905[N]

The value of the surface area of the cylinder is equal to the value of the volume of the cylinder. Find the value of x.
max2010maxim [7]

The volume of a cylinder is given by the formula v=pi r^2h, where r is the radius of the cylinder and h is the height.

<h3>What Does a Cylinder's Surface Area Look Like?</h3>

The overall area or region that the surface of a cylinder covers is referred to as its surface area. A cylinder's total surface area includes both the area of the curved surface and the area of the two flat surfaces because there are two flat surfaces and one curved surface. A cylinder's surface area is measured in square units like m2, in2, cm2, yd2, etc.

<h3>What is the cylinder's total surface area?</h3>

The sum of the curved surface areas makes up the cylinder's overall surface area.
