Humid air breaks down (its molecules become ionized) in an electric field of 4.99 x 10^6 n/c. in that field, what is the magnitude of the electrostatic force on (a) an electron and (b) an ion with a single electron missing? (a) number units (b) number units

Explanation:

It is given that,

Electric field,

The relation between the electric force and the electric field is given by :

Where

q is the charge

(a) Charge on the electron,

Electrostatic force,

(b) If an electron is missing, the net charge remains the same only sign changes.

So, force becomes,  

Hence, this is the required solution.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
