The electric potetnial in a region along x-axis varies with `x` according to the releation `V(x) = 4 xx 5x^(2)`. Then the incorrect statement isA. potential difference between the points x = 1 and x = -2 is 15 V.B. the force experienced by the above charge will be towards the +x-axis.C. a uniform electric field exists in this region along the +x-axis.D. force experienced by a 1 C charge at x = -1 will be 10 N. |

Answer» Correct Answer - A::C::D a.,c.,d. `V(x)=4+5x^(2)` `V(x=1)=9V` And `V(x=-2)=24V` Hence, `DeltaV=15V` `E=-(DeltaV//Deltax)=-10x` `therefore E(atx=-1m)=10NC^(-1)` So, `F=qE=+10N` (along positive `x-` axis). |
