QAIPM-2015-Ph-1258: NEET 2015 Physics - Class 12 AIPM-2015-Ph-1258 Solution: If potential (in volts) in a region is expressed as \(V(x y z)…

If potential (in volts) in a region is expressed as

V(x y z) = 6xy - y + 2yz

the electric field (in N/C) at point (11 0) is

-(2\hat{i}+3\hat{j}+\hat{k})

-(6\hat{i}+9\hat{j}+\hat{k})

-(3\hat{i}+5\hat{j}+3\hat{k})

-(6\hat{i}+5\hat{j}+2\hat{k})

A $- \left( {2\widehat i + 3\widehat j + \widehat k} \right)$ _ ( 2 i + 3 j _ + k )
B $- \left( {6\widehat i + 9\widehat j + \widehat k} \right)$ _ ( 6 i + 9 j _ + k )
C $- \left( {3\widehat i + 5\widehat j + 3\widehat k} \right)$ _ ( 3 i + 5 j _ + 3 k )
D $- \left( {6\widehat i + 5\widehat j + 2\widehat k} \right)$ _ ( 6 i + 5 j _ + 2 k )
