MCQ
$1 \ emu =.......... C$
  • ✓
    $10$
  • B
    $3 \times 10^9$
  • C
    $4.8 \times 10^{-10}$
  • D
    $0.1$
✓

Answer

Correct option: A.
$10$
$1$ emu charge is equal to $10$ -coulomb charge while $1$ coulomb is equal to $3 \times 10^9$ esu charge. Emu and C both are the units of charge and hence their conversion formula is necessary for many numerical problems.
