Complete Question

A proton of mass mp= 1.67×10−27 kg and a charge of qp= 1.60×10−19 C is moving through vacuum at a constant velocity of 10,000 m/s directly to the east when it enters a region of uniform electric field that points to the south with a magnitude of E = 3.62e+3 N/C . The region of uniform electric field is 5 mm wide in the east-west direction. How far (in meters) will the proton have been deflected towards the south by the time it exits the region of uniform electric field. You may neglect the effects of friction and gravity, and assume that the electric field is zero outside the specified region. Answer is to be in units of meters

$s = 0.039 \ m$

Explanation:

From the question we are told that

The mass of the proton is $m = 1.67 *10^{-27} \ g$

The charge of on the proton is $q = 1.60 *10^{-19} \ C$

The speed of the proton is $v = 10000 \ m/s$

The magnitude of the electric field is $E = 3.62*10^{3 } \ N/C$

The width covered by the electric field $d = 5mm = 5 *10^{-3} \ m$

Generally the acceleration of the proton due to the electric toward the south (at the point where the force on the proton is equal to the electric force due to the electric field) is mathematically represented as

$a = \frac{q* E}{m}$

Substituting values

$a = \frac{1.60*10^{-19 } * 3.26 *10^{3}}{ 1.67*10^{-27}}$

$a = 3.12*10^{11} \ m/s^2$

Generally the time it will take the proton to cross the electric field is mathematically represented as

$t = \frac{d}{v}$

Substituting values

$t = \frac{5 *10^{-3}}{10000}$

$t = 5 *10^{-7} \ s$

Generally the the distance covered by the proton toward the south is

$s = ut + \frac{1}{2} * a*t^2$

Here u = 0 m/s this because before the proton entered the electric field region the it velocity towards the south is zero

$s = \frac{1}{2} * a*t^2$

Substituting values

$s = \frac{1}{2} * 3.12 *10^{11}*(5 *10^{-7})^2$

$s = 0.039 \ m$

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?
