Question

1. Find the dimensional formula of strength or intensity of magnetic field B.
( Hint: use the formula of lorentz force .charge q= It( current× time) The dimensional formula of electric current)

Answer 1

Answer:

• Using Coulomb law, 1/4π€0 • q1q2/R²
• €0=q1q2/4πFR²
• Substituting the units in the equation:
• So, €0=C²/n•m²
