if electric potential at a point in space is given by v=A(xy+yz +zx) and v at (2,-1,8) is 120 volts find electric potential at a point (1,2,3).

Answers : (2)


just substitute x,y,z in the eqn and u get A=20

now dat A=20,again substitute x,y,z = 1,2,3 resp and u get v=20*11= 220

plzzz approve my answer if u like it

simply put the values

120  =A( 2*(-1) + (-1) *8 + 8 *(2))

120  = A(6)

=>  A = 20.


so again for (1,2,3) 

v  =  20 (1*2 + 2*3 + 3* 1)

v = 220v
