Question
Download Solution PDFA proton is about 1840 times heavier than an electron. When it is accelerated by a potential difference of 1KV, its kinetic energy will be
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
By conservation of energy,
The kinetic energy has to equal the change in potential energy, so
KE = q ×V
Calculation:
Given that,
Mass of proton = 1840 × mass of electron
Potential difference (ΔV) = 1KV
By using the above concept
(KE)final - (KE)initial = Charge on proton × ΔV
(KE)final -0 = (+e) × ΔV
(KE)final = 1 KeV
∴ The required kinetic energy will be 1 KeV.
