Calculate the force on a unit positive charge at p on x axis whose co-ordinates are (x=2m,y=0) due to the following two charges
Xelga [282]

The force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.

<h3>Force on the charge</h3>

The force on the charge is calculated as follows;

F = k(q1q2)/r²

where;

  • r is the distance between the charges = 2 m - 1m = 1m

F = (9 x 10⁹ x 10⁻⁹ x 2 x 10⁻⁹)/(1)²

F = 1.8 x 10⁻⁸ N

Thus, the force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.

A rock formed with 1,000 atoms of a radioactive parent element, but only contains 250 radioactive parent atoms today. If the hal
alisha [4.7K]

Answer:

age of rock is 2 million years

Explanation:

M_{R}=\frac{M_{O} }{2^{n} }

Where M_{R} is mass remaining

            M_{R} is original mass

         n= t/t(1/2) , which is the ratio of time to half life

M_{O} = 1000atoms

M_{R} =250 atoms

250 =\frac{1000}{2^{n} }

2^{n} = \frac{1000}{250}\\  2^{n} =4\\2^{n}  = 2^{2}\\ n=2

n =\frac{t}{t\frac{1}{2} }

t =t(1/2) *n

t(1/2) =1000000 years

t=1000000 *2

t=2,000,000 years
