(a) two ions with masses of 4.39×10^−27 kg move out of the slit of a mass spectrometer and into a region where the magnetic field is 0.301 t. each has a speed of 7.92 × 10^5 m/s, but one ion is singly charged and the other is doubly charged. find the radius of the circular path followed by the singly charged ion in the field. answer in units of cm. (b) find the radius of the circular path followed by the doubly charged ion in the field. (c) find the distance of separation when they have moved through one-half of their circular path and strike a piece of photographic paper.

Part a)

Part b)

Part c)

d = 0.072 m

Explanation:

Part a)

As we know that the radius of the charge particle in constant magnetic field is given by

now for single ionized we have

Part b)

Similarly for doubly ionized ion we will have the same equation

Part c)

The distance between the two particles are half of the loop will be given as

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
