Question

Answer True or False to each case. Coulomb's law states that the force between static charges Q1 and Q2 Trute B is a force of attraction. True B is proportional to 1/r. True is proportional to Q1 Q2 True B is K Q1Q2/r where K is a universal constant. True B is proportional to the total charge Q1+02 Submit Anawer Incor Tries 7/20 Previous Tries TPost Discussion Send Feedback cBook Pro 4 5 6 2 3 option command

Answer 1

According to Coulomb's Law ,forces between static charges Q₁ and Q₂ is

$F=kQ_{1}Q_{2}/r^{2}$

Option 1 is False

Forces can be attractive or repulsive,it depends on the charges.

Like charges repel and unlike charges attracts.

-------------------------

Option 2 is false

Force is proportional to $1/r^{2}$

-----------------------

Option 3 is True

---------------------

Option 4 is false

$F=kQ_{1}Q_{2}/r^{2}$

not ${\color{Red} F=kQ_{1}Q_{2}/r}$

------------------------

Option 5 is false

F is proportional to $Q_{1}Q_{2}$

not $Q_{1}+Q_{2}$
