What is the velocity of a beam of electrons that go undeflected when passing through crossed (perpendicular) electric and magnetic fields of magnitude 1.58×104V/m and 2.40×10−3T, respectively? me=9.11×10−31kg, e=1.60×10−19C. Express your answer to three significant figures and include the appropriate units.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

because growing process had stoped after 4-5 year

well clustered together.
