Question
According to Rutherford, α-particles gets deflected by:
- Large amount
- Sometimes large, sometimes small
- Sometimes small
- Very small amount
Hint:
Alpha particles are deflected by a magnetic field confirming that they must carry a charge. The direction of deflection which can be determined by Fleming's left hand rule demonstrates that they must be positively charged.
The correct answer is: Large amount
In Rutherford's α-particle scattering experiment, most of the α-particles were deflected by nearly 1800. Reason: The positive charge of the atom is spread throughout the atom that repelled and deflected the positively charged α-particles.
