A charge of 31 micro-C is placed on the y axis at y = 8 cm and a 55 micro-C charge is placed on the x axis at x = 3 cm. If both charges are held fixed, what is the magnitude of the initial acceleration of an electron released from rest at the origin? Write your answer in terms of 10^18 m/s2.

The value is

Explanation:

From the question we are told that

The magnitude of the first charge is

The position is y = 8 cm = 0.08 m

The magnitude of the second charge is

The position is x = 3 cm = 0.03 m

Generally the force exerted on the electron by the first charge is mathematically represented as

Here k is the coulombs constants with value

=>

and e is the charge on a electron with value

So

Generally the force exerted on the electron by the first charge is mathematically represented as

=>

=>

Generally the net force exerted is mathematically represented as

So

The resultant of this net force is mathematically represented as

Generally this force can be represented as

Here m is the mass of the electron with value

=>      

=>

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

i think its c if i'm wrong
