How is electric potential related to distance? r^2 r 1/r 1/(r^2). Is electric potential scalar or vector vector scalar. If a charge of +1C is placed at a distance of 0.5m in an electric field due to charge of +100nano-C then electric potential would be[1nano=10^-9m] 1800V 3.6V 0.036V None of the above. What is the relation between electric field strength and electric potential? E=Vr V=E/r r=EV E=- v/r. How do we define electric potential? It is the product of current and resistance. it is the loss of energy when current passes It is the amount of work done to move a charge from infinity to a point. It is same as electric field strength. An electron is accelerated by 9MeV energy. Determine the velocity if mass is 9.1 x 10^-31kg. [Charge is 1.6x10^-19C] 1.77x10^9 1.11x10^9 1.77x10^7 None of the above. If two similar charges (+3.2C) are placed 20cm apart then where will the net effect be zero? At10cm from right At 5cm from right At 5cm from left Data is not enough to determine the position. Which among the below is not unit of electric potential? joule/C N/m eV MeV. If potential difference between plate separated by 0.2m is 20V then the electric field strength would be [N/C] 10 1000 1 100. How is uniform electric field different from non-uniform electric field? Uniform field starts from a point and ends at a point [when two point charge is separated] In Uniform field the flux(field lines ) are parallel to each other Non Uniform the flux (field lines ) are parallel None of the above describes the actual answer.
