Solution
F=(kq1q2)/r2
a)
1)F=(k*2q*2q)/d2=(4kq2)/d2
2)F=(k*3q*q)/d2=(3kq2)/d2
3)F=(k*q*q)/d2=(kq2)/d2
order is 1>2>3
--------------------------------
b)
1)F=(k*q*q)/d2=(kq2)/d2
2)F=(k*q*q)/d2=(kq2)/d2
3)F=(k*q*q)/d2=(kq2)/d2
magnitude of all forces are same
--------------------------------
c)
1)F=(k*q*q)/d2=(kq2)/d2
2)F=(k*q*q)/(2d)2=(kq2)/4d2
3)F=(k*q*q)/(3d)2=(kq2)/9d2
order is 1>2>3
--------------------------------
