The nucleus of a hydrogen atom, a proton, sets up an electric field. The distance between the proton and electron is about 5.1  10-11 m. What is the magnitude of the electric field at this distance from the proton? The charge on the proton is +1.6  10-19 C.

Question 2

A proton moving at 3  104 m/s is projected at an angle of 30 above a horizontal plane. If an electric field of 400 N/C is directed downwards, how long does it take the proton to return to the horizontal plane? (HINT: Ignore gravity.) mProton = 1.67  10-27 kg, qProton = +1.6  10-19 C.

Though methadone is often used to treat dependency on other opioids, the drug itself can be abused. Crushing or snorting methadone can achieve the opiate "rush" desired by addicts. Improper use such as these can lead to a dangerous dependency on methadone. This drug now accounts for nearly one-third of opioid-related deaths.
