The magnitude of electric field intensity due to a point charge is 10 N/C at a distance 1 m from it. Calculate the magnitude of charge.

Explanation

To solve the problem of finding the magnitude of charge given the electric field intensity, we can use the formula for the electric field intensity (E) due to a point charge (Q):

\[ E = \frac{k \cdot |Q|}{r^2} \]

where:
- \( E \) is the electric field intensity,
- \( k \) is Coulomb's constant (\( 8.99 \times 10^9 \, \text{N m}^2/\text{C}^2 \)),
- \( |Q| \) is the magnitude of the charge,
