Two flawlessly conducting spheres are in an evacuated region of space. One is at a potential of 12 volts as well as the other is at a potential of 15 volts. A free electron is released as of rest at the surface of the sphere at -12 volts. With what speed does it collide into the other sphere? (The mass of an electron is 9.11 × 10-31 kg.)

As we''re on an inclined plane shouldn''t we take the x & y components of gravity into consideration?? thanks
If either screen or source or both are at preset distance from the diffracting device (obstacle or aperture), the diffraction is known as Fresnel type.
WORK AND ENERGY 1. Work can be defined as: the force applied in direction of displacement ×. This means that if the force F acts at an angle θ with respect to the direct
