Question

Calculate coloumbic force between w two alpha particles

Answer 1

Explanation:

Charge of alpha particle = 2e

Here e = charge of electron

F = kq₁q₂/r²

= 4ke²/r²

= 4 × (9 × 10⁹) × (1.6 × 10⁻¹⁹)² / (3.2 × 10⁻¹⁵)²

= 90 N

Coulombic Force between them is 90 N

Answer 2

Charge of alpha particle = 2e

Here e = charge of electron

F = kq₁q₂/r²

= 4ke²/r²

= 4 × (9 × 10⁹) × (1.6 × 10⁻¹⁹)² / (3.2 × 10⁻¹⁵)²

= 90 N

Coulombic Force between them is 90 N
