Answer: 94.9 metres
Explanation:
Given that,
Force between the two charges (F) = 24x10² N
Negative charge (q1) = 8x10-5C
Positive charge (q2) = 3x10C
Distance between charges (r) = ?
Apply the formula for
F= (kq1q2) / r²
Recall that k is Coulomb's constant with a value of 9 × 10^9 Nm2C−2
Then,
24x10² N = (9 × 10^9 Nm2C−2 x 8x10-5C x 3x10C) / r²
24x10² N = (2.16 x 10^7) / r²
r² = (2.16 x 10^7 / 24x10² N)
r² = 9000
To get the value of r, find the square root
r = √9000
r = 94.868m (rounded to the nearest tenth as 94.9m)
Thus, a distance of 94.9 metres separates the charges.
