Question

According to coulomb's law, rank the interactions between charged particles from highest potential energy to lowest potential energy.rank from highest to lowest potential energy. to rank items as equivalent, overlap them.1. 1+ charge and 1- charge seperated by 200pm2. 1+ charge and 1+ charge seperated by 100pm3. 1+ charge and 1- charge seperated by 100pm4. 2+ charge and 1- charge seperated by 100pm

Answer 1

Answer: (2) > (1) > (3) > (4)

Step-by-step explanation:

(1) a +1 charge and a -1 charge separated by 200 pm:

The potential energy in this case will be,

`U_E & = k\;\rm (N\cdot m^2/C^2) ((+1 \ C)(-1 \ C))/(200 * 10^(-9) \ m ) \\ & = - (1)/(2)k * 10^7 \ \rm J`

(2) a +1 charge and a +1 charge separated by 100 pm:

The potential energy in this case will be,

`U_E & = k\;\rm (N\cdot m^2/C^2) ((+1 \ C)(+1\ C))/(100 * 10^(-9) \ m ) \\ & = k * 10^7 \ \rm J`

(3) a +1 charge and a -1 charge separated by 100 pm:

The potential energy in this case will be,

`U_E & = k\;\rm (N\cdot m^2/C^2) ((+1 \ C)(-1 \ C))/(100 * 10^(-9) \ m ) \\ & = - k * 10^7 \ \rm J`

(4) a +2 charge and a -1 charge separated by 100 pm:

The potential energy in this case will be,

`U_E & = k\;\rm (N\cdot m^2/C^2) ((+2 \ C)(-1 \ C))/(100 * 10^(-9) \ m ) \\ & = - 2k * 10^7 \ \rm J`

So, the order from highest potential energy to lowest potential energy is:

(2) > (1) > (3) > (4)
