Answer» tion:ANSWERLet the charge of proton is qCharge of α−particle=2×chargeofproton=2qThe force acting between TWO protons SEPARATED by a DISTANCE r ISF=k r 2 q⋅q =k r 2 q 2 The force acting between two α− patricles separated by a distance 2r isF ′ =k (2r) 2 2q⋅2q =k 4r 2 4Q 2 or =k r 2 r 2 ⇒F ′ =F |
