Question

An electron is accelerated through a potential difference ΔV and projected into a perpendicular and uniform magnetic field. In another experiment, the accelerating potential difference is increased to four times of its initial value, then

एक इलेक्ट्रॉन को विभवान्तर ΔV से त्वरित किया जाता है तथा इसे किसी लम्बवत् व एकसमान चुम्बकीय क्षेत्र में प्रक्षेपित किया जाता है। अन्य प्रयोग में, त्वरक विभवान्तर को इसके प्रारम्भिक मान के चार गुना तक बढ़ाया जाता है, तब

A
Radius of path traversed by the electron becomes double

इलेक्ट्रॉन द्वारा तय किए गए पथ की त्रिज्या दोगुनी हो जाती है
