Answer:
q = 1.96 10⁴ C
Explanation:
The elective force is given by
= q E
Where E is the electric field and q the charge.
Let's use Newton's law of equilibrium for the case of the suspended drop
F_{e} –W = 0
F_{e} = W
q E = m g
q = m g / E
Let's calculate
q = 2.0 10⁵ 9.8 / 100
q = 1.96 10⁴ C
Answer:
B
Explanation:
acceleration = change in speed / change in time
for 1, speed increases over time, so positive acceleration
for 3, speed decreases over time, so negative acceleration (or deceleration)
The fraction of the magnitude of the kinetic energy lost is . = 0.955.
using the law of conservation of momentum,
kinetic energy lost,
Δ
(see image )
now, for the other part
the fraction of the kinetic energy lost,
ΔKE/ KE =
ΔKE/ KE =
ΔKE/ KE = 0.955.
what is kinetic energy ?
The energy that an object has as a result of motion is known as kinetic energy. It is stated as the effort needed to transfer a bulk body from rest to the given velocity. The body holds onto the kinetic energy it gained during its acceleration until its speed changes.
