Teaching MPPSC Assistant Professor Mock Test Series 2025 Physics Electric Fields and Gauss' Law Electric Field
A conductor of length 100 cm and area of cross section 1 mm2 carries a current of 5 A. If the resistivity of the material of the conductor is 3.0 × 10−8 Ω m, then the electric field across the conductor is
1
0.15 V/m
2
0.015 V/m
3
1.5 V/m
4
0.0015 V/m
