An electron is placed 5.40 cm due north of a charged sphere and experienced a force of 8.30 x 10^-13 N due north. What is the electric field experienced by the electron at that point?

The electric field is

Explanation:

The force on a charge in an electric field is given by

,

which can be rearranged to give

Now, the force on the electron is , and its charge is

; therefore,

Mass of larger cart will be 0.0213 m /sec

Explanation:

We have given mass of small cart

Initial velocity of small cart

Mass of larger block

Initial velocity of larger cart

After the collision velocity of smaller cart

Now according conservation of momentum
