A 1,198 N sky diver has opened his parachute to slow his descent to a constant speed the parachute applies 1,277 N of force. He

experiences a 7.5 m/s2 deceleration. What is the mass of the sky diver?

The mass of the skydiver is 122.2 kg

Explanation:

We can solve the problem by using the concept of weight.

The weight of a body is the force of gravity acting on the body; near the Earth's surface, its magnitude is given by

W=mg

where

m is the mass of the body

g=9.8 m/s^2 is the acceleration of gravity

In this problem, we know the weight of the skydiver:

W = 1198 N

So we can re-arrange the equation to find its mass:

m=\frac{W}{g}=\frac{1198}{9.8}=122.2 kg

Two 2.0-cm-diameter insulating spheres have a 6.60 cm space between them. One sphere is charged to + 76.0 nC , the other to - 30
e-lub [12.9K]

Answer:

5.2\times 10^5N/C

Explanation:

Since the two charged bodies are symmetric, we can calculate the electric field taking both of them as point charges.

This can be easily seen if we use Gauss's law, \int{E} \, dA=\frac{Q_{enclosed}}{\epsilon_o}

We take a larger sphere of radius, say r, as the Gaussian surface. Then the electric field due to the charged sphere at a distance r from it's center is given by,

E=\frac{1}{4\pi r^2} \frac{Q_{enclosed}}{\epsilon_o}

which is the same as that of a point charge.

In our problem the charges being of opposite signs, the electric field will add up. Therefore,

E_{total}=\frac{1}{4\pi\epsilon_o}\frac{q_1+q_2}{r^2}= (9\times10^9) \frac{(76+30)\times10^{-9}}{((1+3.3)\times10^{-2})^2}N/C =5.2\times10^5N/C

where, r = distance between the center of one sphere to the midpoint (between the 2 spheres)
