Question

Four identical metallic objects carry the following charges 1.08 6.74 4.61 and 9.41 C The objects are brought simultaneously into contact so that each touches the others Then they are separated a What is the final charge on each object b How many electrons or protons make up the final charge on each object

Answer 1

(a) 5.46 C

(b) 3.4125 x 10^19

Step-by-step explanation:

q' = 1.08 C, q'' = 6.74 C, q''' = 4.61 C, q'''' = 9.41 C

When the charges are in contact to each other.

(a) So, the net charge is

`q = (q' + q'' + q''' + q'''')/(4)`

`q = (1.08+6.74+4.61+9.41)/(4)\\\\q = 5.46 C`

(b) As the charge is positive in nature, so the protons are there. The number of protons is

`n = (q)/(e)\\\\n = (5.46)/(1.6* 10^(-19))\\\\n = 3.4125* 10^(19)`
