Suppose all the electrons of 100 g water are lumped together to form a negatively charged particle and all the nuclei are lumped together to form a positively charge particle. If these two particles are placed 10.0 cm away from each other, fien the force of attraction between them. Compare it with your weight.

Text Solution

Verified by Experts

No. of electrons in `100 gm H_2O`
` =3.34xx10^25 `
and total charge of electron in `100 gm`
` water=-5.34xx10^6C `
Similarly, Total charge of protons in `100 gm=+5.34xx10^6C `
Hence electrical force
` =9xx10^9xx(5.34xx 10^6xx5.34xx10^6)/10^-2 `
` =2.56xx10^25 Newtons`

Scientists are working hard to develop nuclear fusion reactor Nuclei of heavy hydrogen, _(1)^(2)H , known as deuteron and denoted by D , can be thought of as a candidate for fusion rector . The D-D reaction is _(1)^(2) H + _(1)^(2) H rarr _(2)^(1) He + n+ energy. In the core of fusion reactor, a gas of heavy hydrogen of _(1)^(2) H is fully ionized into deuteron nuclei and electrons. This collection of _1^2H nuclei and electrons is known as plasma . The nuclei move randomly in the reactor core and occasionally come close enough for nuclear fusion to take place. Usually , the temperature in the reactor core are too high and no material will can be used to confine the to plasma for a time t_(0) before the particles fly away from the core. If n is the density (number volume ) of deuterons , the product nt_(0) is called Lawson number.

Consider a sphere of radius R with charge density distributed as : rho( r) =kr, r le R =0 for r gt R (a) Find the electric field at all points r. (b) Suppose the total charge on the sphere is 2e where e is the electron charge. Where can two protons be embedded such that the force on each of them is zero. Assume that the introduction of the proton does not alter the negative charge distribution.

Flow cytometry, illustrated in the figure, is a technique used to sort cells by type. The cells are placed in a conducting saline solution which is then forced from a nozzle. The stream breaks up into small droplets, each containing one cell. A metal collar surrounds the stream right at the point where the droplets seprate from the stream. Charging the collar polarizes the conducting liquid, causing the droplets to become charged as they break off from the steam. A leser beam probes the solution just upstream from the charging collar, looking for the presence of certain types of cells. All droplets containing one particular type of cell are given the same charge by the charging collar. Droplets with other desired types of cells receive a different charge, and droplats with no desired cell receive no charge. The charged. The charges droplets then pass between two parallel charged electrodes where they receive a horizontal force that directs force that directs them into different collection tubes, depending on air charge.

The charges droplets then pass between two parallel charged electrodes where they receive a horizontal force that directs force that directs them into different collection tubes, depending on air charge. Another way to sort the droplets would be to given each droplet the same charge, then vary the electric field between the deflection plates. For the apparatus as sketched, this technique will not work because
