ಉತ್ತರ ತೋರಿಸು ಮತ್ತು ವಿವರಣೆ
ಉತ್ತರ: (D) Newton per ampere-metre
ವಿವರಣೆ
Using F = BIL, the tesla equals one newton per ampere-metre.
- (A) ತಪ್ಪು
Wrong: dimensionally wrong.
- (B) ತಪ್ಪು
Wrong: that is the unit of electric field.
- (C) ತಪ್ಪು
Wrong: A·s is a coulomb; missing velocity term.
- (D) ಸರಿ
Correct: from F = BIL, B = F/(IL), so T = N/(A·m).
