To find the charge that produces an electric field strength (E) of 40 V/cm at a distance (r) of 30 cm in a vacuum, we can use the formula for the electric field due to a point charge:[E = frac{k cdot |q|}{r^2}]Where:- (E) is the electric field strength (in V/m),- (k) is Coulomb's constant, approximaRead more
To find the charge that produces an electric field strength (E) of 40 V/cm at a distance (r) of 30 cm in a vacuum, we can use the formula for the electric field due to a point charge:
[
E = frac{k cdot |q|}{r^2}
]
Where:
– (E) is the electric field strength (in V/m),
– (k) is Coulomb’s constant, approximately (8.99 times 10^9 , text{N m}^2/text{C}^2),
– (q) is the charge (in coulombs),
– (r) is the distance from the charge (in meters).
Step 1: Convert units
– (E = 40 , text{V/cm} = 4000 , text{V/m})
– (r = 30 , text{cm} = 0.3 , text{m})
Step 2: Rearrange the formula to solve for charge (q)
[
|q| = frac{E cdot r^2}{k}
]
Step 3: Substitute the values
[
|q| = frac{4000 , text{V/m} cdot (0.3 , text{m})^2}{8.99

To determine the distance between the two charges, we can use Coulomb’s Law, which is given by the formula:
[
F = k frac{|q_1 q_2|}{r^2}
]
where:
– ( F ) is the force between the charges (0.1 N),
– ( k ) is Coulomb’s constant (( 8.99 times 10^9 , text{Nm}^2/text{C}^2 )),
– ( q_1 ) and ( q_2 ) are the magnitudes of the charges (( 2 times 10^{-7} , C ) and ( 4.5 times 10^{-7} , C ), respectively),
