1. Electric Charges and Fields
easy
આકૃતિ વિદ્યુતક્ષેત્ર સાથે (સંલગ્ન) કેટલીક વિદ્યુત રેખાઓ દર્શાવે છે. તો......
A
$E_A > E_B > E_C$
B
$E_A = E_B = E_C$
C
$E_A = E_C > E_B$
D
$E_A = E_C < E_B$
Solution
The line density in electric field lines give the information of strength or magnitude of an electric field. Here line density in electric field lines at $A$ and $C$ is same. So the electric filed at $A$ and $C$ will be same. i,e $E_A=E_C$
As line density at $A$ and $C$ is greater than at the line density at $B$ so $E_A=E_C > E_B$
