Answer:
6000 N toward west
Explanation:
F = ma
a = 30-15/10 = 1.5 m/s^2 towards west
m = 4000 kg
F = 4000 x 1.5 = 6000 N towards west
Answer:
a) 74.8 V/m
b) direction -(i)
Explanation:
For this case, the electric field is defined as:
because V is a function dependent of x so we can derivate it:
so:
Because of the sign, the magnitude of electric field 74.8 V/m on the negative direction of i vector, thus means towards the plate 1.
