In the formula X = 5 Y Z 2 , X and Z have dimensions of capacitance and magnetic field, respectively. What are the dimensions of Y in SI units?

Options

  1. AM - 1 L - 2 T 4 A 2
  2. BM - 2 L 0 T - 4 A - 2
  3. CM - 2 L - 2 T 6 A 3
  4. DM - 3 L - 2 T 8 A 4

Correct answer

D. M - 3 L - 2 T 8 A 4

Step-by-step solution

Y = X Z 2 = M - 1 L - 2 T 4 A 2 M L 0 T - 2 A - 1 2 = M - 3 L - 2 T 8 A 4
