एक प्रकोष्ठ में \( 6.5 \mathrm{G}\left(1 \mathrm{G}=10^{-4} \mathrm{~T}\right) \) का एकसमान चुंबकीय क्षेत्र बनाए रखा गया है। इस चुंबकीय क्षेत्र में एक इलेक्ट्रॉन \( 4.8 \times 10^{6} \mathrm{~m} \mathrm{~s}^{-1} \) के वेग से क्षेत्र के लंबवत भेजा गया है। व्याख्या कीजिए कि इस इलेक्ट्रॉन का पथ वृत्ताकार क्यों होगा? वृत्ताकार कक्षा की त्रिज्या ज्ञात कीजिए। \( \left(e=1.6 \times 10^{-19} \mathrm{C}, m_{e}=9.1 \times 10^{-31} \mathrm{~kg}\right) \)
