For each quantity listed, indicate dimensions using force as a primary dimension, and give typical SI and English units: (a) Power (b) Pressure (c) Modulus of elasticity (d) Angular velocity (e) Energy (f) Momentum (g) Shear stress (h) Specific heat (i) Thermal expansion coefficient (j) Angular momentum

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
