Due to a charge inside the cube, the electric field is: `E_(x)` = 600x, `E_(y)` = 0, `E_(z)` = 0. The charge inside the cube is nearly - A. 600`mu`CB. 60`mu`CC. 53`mu`CD. 6`mu`C

Answer» Correct Answer - C
`q=varepsilon_(0)(Q_(2)-Q_(1))`
`phi_(2)=E_(2).A`
`phi_(2)=600xx0.2xx0.01=1.2`
`phi_(1)=600xx0.1xx0.01=0.6`
`q=8.85xx10^(-12)xx0.6`
`q=53.10xx10^(-12)`
