What is the magnitude of the acceleration of a modified atwood machine if the mass of the cart is 2 kg and the hanging mass is 17 kg? (use g = 9.8 m/s2. express your answer to one decimal point?

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
