NASA is going to launch a rocket to Mars, with the rocket blasting off from the Earth when the Earth and Mars are aligned along

a straight line from the Sun. If the Mars is now 60° ahead of the Earth in its orbit around the
sun, when should they launch the rocket? All the planets orbit the sun in the same direction and 1 year on Mars is 1.9 Earth-years. Assume circular orbits for the Earth and the Mars.

What is the magnitude of an electric field that balances the weight of a plastic sphere of mass 2.1 g that has been charged to -
Liula [17]

Answer:

Electric field, E=6.86\times 10^6\ N/C

Explanation:

It is given that,

Mass of sphere, m = 2.1 g = 0.0021 kg

Charge, q=-3\ nC=-3\times 10^{-9}\ C

We need to find the magnitude of electric field that balances the weight of a plastic spheres. So,

ma=qE

a = g

E=\dfrac{mg}{q}

E=\dfrac{0.0021\ kg\times 9.8\ m/s^2}{-3\times 10^{-9}\ C}

E=6860000\ N/C

or

E=6.86\times 10^6\ N/C

Hence, the magnitude of electric field that balances its weight is 6.86\times 10^6\ N/C. Hence, this is the required solution.
