A proton in a particular electric field experiences an electric force whose magnitude is equal to the weight of the proton. Dete

gavmur [86]

Answer:

Electric field, $E=10^{-7}\ N/C$

Explanation:

It is given that, a proton in a particular electric field experiences an electric force whose magnitude is equal to the weight of the proton such that,

$qE=mg$

$E=\dfrac{mg}{q}$

$E=\dfrac{1.67\times 10^{-27}\times 9.8}{1.6\times 10^{-19}}$

$E=1.02\times 10^{-7}\ N/C$

$E=10^{-7}\ N/C$

So, the magnitude of electric field at the location of the proton is $10^{-7}\ N/C$ . Hence, this is the required solution.

How much work was done to accelerate a 2.2 kg object from rest to 26m/s?

Makovka662 [10]

Answer:

Explanation:

work done = change in kinetic energy, assuming there are no energy losses.

work done = 1/2 × m × change in v^2

= 1/2 × 2.2 × ( 26^2 - 0^2)

= 1/2 × 2.2 × 676

= 743.6 joules
