A toy rocket engine is securely fastened to a large puck that can glide with negligible friction over a horizontal surface, taken as the xy plane. The 5.40-kg puck has a velocity of 2.00î m/s at one instant. Eight seconds later, its velocity is (6.00î + 4.0ĵ) m/s. (a) Assuming the rocket engine exerts a constant horizontal force, find the...

4. a- A Gaussian sphere with radius 1.20 m encloses a point charge Q1 = 2.20×10–6 C at the spherical center. The electric flux through the spherical surface is measured to be 1. Now Q1 is removed, and another point charge Q2 = –8.80×10–6 C is placed at the spherical center. The electric flux through the spherical surface is then...

Two sheets have opposite charge densities (charge per unit area) and are parallel to one another to form a parallel plate capacitor. One of the sheets contains 3.6 micro-coulombs of charge in a 0.46 m2 area. What is the magnitude of the electric field in 10^5 N/C in between the sheets of the capacitor?
