Print Calculator Periodic Table Question 21 of 36 Map Sapling Learning An isolated, irregularly shaped piece of platinum carries -7.61 x10° C of charge and is in electric equilibrium. The size of this body is about 4 mm. When the electric potential at some point on the metal's surface has the value V, the potential at a different point on the surface (indicate one); O may equal V. O equals v O always differs from V When the electric field strength at some point on the body's surface has the value E, the field strength ata different point on the surface (indicate one) O equals E O equals O. O always differs from E O may equal E. Calculate the potential at a distance of 5.67 m from the center of the charged piece of platinum. Number Hint O Previous e Check Answer Exit Next

Explanation / Answer

Potential at some other point it may Equal V
so the answer is may equal V

if V may Equal then E is also may Equal

so the answer is may equal E

at r = 5.67 m

then

V = k*q/r = 9*10^9*7.61*10^-9/(5.67) = 12.1 V
