रुदरफोर्डच्या सुवर्णपत्री प्रयोगाचे एक निरीक्षण. “काही α-कणांचे काही कोनातून विचलन झाले” ह्याचे कारण α-कण वरीलपैकी कोणते/ती विधान/ने बरोबर आहे/आहेत. / One of the observations of Rutherford's thin gold foil experiment was "some α-particles got deflected by some angle". The reason was α-particles. The correct option/s is are
(a)अणुकेन्द्रकाच्या जवळ आले. / came closer to the nucleus.
(b)इलेक्ट्रॉन्स कडे आकर्षित झाले. / were attracted towards electrons.
(c)इलेक्ट्रॉन्सवर आढळले. / collided with the electrons.
In Rutherford's experiment, alpha particles are positively charged. When they came close to the positive nucleus, they experienced electrostatic repulsion and got deflected.
