An electron is pushed into an electric field from infinity where it acquires a 1-v electrical potential. suppose instead that two electrons are pushed from infinity the same distance into the same electric field. the electrical potential of the two electrons is

a) 0.5v
b) 1v
c) 0.25v
d) 4v
e) 2v

The electrical potential of the two electrons is 1 V.

(b) is correct option.

Explanation:

Given that.

Electric potential = 1 V

We know that,

The electric potential depends on the distance.

The electric potential does not depend on the charge.

The formula of electric potential

Where, E = electric field

d = distance

Hence, The electrical potential of the two electrons is 1 V.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
