Expert Solution & Answer
Check Mark

Explanation of Solution

Given:

Charge on particle 1, q1=+75μC

Charge on particle 2, q2=+48μC

Charge on particle 3, q3=85μC

Distance between particle 1 and 2, d12=0.35m

Distance between particle 1 and 3, d13=0.70m

Distance between particle 2 and 3, d23=0.35m

Formula used:

Electric force can be obtained by:

  F=kq1q2r2

Here, k is the Coulomb’s constant, q1 and q2 are the charges and ris the distance between them.

Calculation:

Force on particle 1 due to other two:

  F12+F13=kq1q2d122+kq1q3d132F12+F13=9×109×75×106(48×1060.352+85×1060.702)F12+F13=675×103(391.84173.47)F12+F13=147.4N

Force on particle 2 due to other two:

  F21+F23=kq1q2d122+kq2q3d232F21+F23=9×109×48×106(75×1060.352+85×1060.352)F21+F23=432×103(612.24693.88)F21+F23=35.27N

Force on particle 3 due to other two:

  F13+F23=kq1q3d132+kq2q3d232F13+F23=9×109×(85×106)(75×1060.702+48×1060.352)F13+F23=765×103(153.06+391.84)F13+F23=416.85N
