Physics Question from JEE Main 2025 · 29 January, Shift 2

A point charge causes an electric flux of −2×104 N m2C−1-2 \times 10^4 \, \text{N m}^2\text{C}^{-1} to pass through a spherical Gaussian surface of 8.0 cm8.0 \, \text{cm} radius, centred on the charge. The value of the point charge is:

(Given ε0=8.85×10−12 C2N−1m−2\varepsilon_0 = 8.85 \times 10^{-12} \, \text{C}^2\text{N}^{-1}\text{m}^{-2})

  • A

    −17.7×10−8 C-17.7 \times 10^{-8} \, \text{C}

  • B

    −15.7×10−8 C-15.7 \times 10^{-8} \, \text{C}

  • C

    17.7×10−8 C17.7 \times 10^{-8} \, \text{C}

  • D

    15.7×10−8 C15.7 \times 10^{-8} \, \text{C}
