Answer:

Explanation:

Force on electron in an electric field E = eE where E is electric field .

acceleration = eE / m where m is mass of electron .

Putting the values

4 x 10⁶ = 1.6 x 10⁻¹⁹ x E / 9.1 x 10⁻³¹

E = 22.75 x 10⁻⁶ N/C

The direction of electric field will be towards west ( opposite to east )

because of negative charge on electron .

Please explain in simple terms why a purple flower appears purple when a white light shines on it?
AleksAgata [21]
The white light is made up of all wavelength of electromagnetic spectrum, the spectrum has different colors, When light rays fall on an object, some of the color in the white light will be absorbed by the object while some will be reflected. The color that is reflected by the object is the one that an observe will see. Thus, a purple flower will appear purple because it is reflecting the wavelength that appear as purple

A ball of mass 2 kg is kept on the hill of height 3 km. Calculate the potential energy possessed by it ?
zysi [14]
We know that -

P.E=m*g*h

Where,

m = mass

g = acceleration due to gravity

h=height

First we convert height into meters.

1 km = 1000 meters

3 km = 1000 * 3 meters = 3000 meters

So, putting the values in the above formula, and by taking 'g' = 9.8 m/s², we get-

P.E.= 2*3000*9.8

P.E.= 58800 Joules

P.E.= 58.8 kJ
