Chapter 3: Q40P (page 126)

At a particular instant a proton exerts an electric force of on an electron. How far apart are the proton and the electron?

Short Answer

Expert verified

The proton and the electron areapart.

Step by step solution

01

Identification of the given data

The given data can be listed below as,

  • The proton exerts an electric force of

02

Significance of the Coulomb’s law for the distance

The coulomb鈥檚 law states that the force exerted by an object is inversely proportional to their distance鈥檚 square and directly proportional to the product of their charges.

The equation of the force gives the distance amongst the proton and the electron.

03

Determination of the distance between proton and electron

From Coulomb鈥檚 law, the electric force on the electron by the proton is expressed as:

Here, F is the magnitude of the electric force that is ; k is the coulomb鈥檚 constant that is about are the charges of the proton and the electron that are and r is the distance amongst them.

Substituting the values in the above equation, we get-

Thus, the proton and the electron areapart.

You hang from a tree branch, then let go and fall toward the Earth. As you fall, the y component of your momentum, which was originally zero, becomes large and negative. (a) Choose yourself as the system. There must be an object in the surroundings whose y momentum must become equally large, and positive. What object is this? (b) Choose yourself and the Earth as the system. The y component of your momentum is changing. Does the total momentum of the system change? Why or why not?

Two balls of mass 0.3kgand0.5kgare connected by a low-mass spring (Figure 3.63). This device is thrown through the air with low speed, so air resistance is negligible. The motion is complicated: the balls whirl around each other, and at the same time the system vibrates, with continually changing stretch of the spring. At a particular instant, the 0.3kgball has a velocity (4,-3,2)鈥�m/sand the0.5kgball has a velocity (2,1,4)鈥�m/s.a) At this instant, what is the total momentum of the device? b) What is the net gravitational (vector) force exerted by the earth on the device? c) At a timelater, what is the total momentum of the device?
