⟹v=20 m/s
The current will increase at the same rate the voltage does.
Explanation:
It is given that,
Electric field,
The relation between the electric force and the electric field is given by :
Where
q is the charge
(a) Charge on the electron,
Electrostatic force,
(b) If an electron is missing, the net charge remains the same only sign changes.
So, force becomes,
Hence, this is the required solution.
Answer:
horse power of the truck 39,000 kgm²s⁻³
Explanation:
Calculate horse power of the truck.
Work = force x distance
where, force = mg = 2000 kg x 9.8 m/s² = 19,600 kgm/s²
distance = 10 meter
Work = 19,600 kgm/s² x 10 meter
= 196,000 kgm²s⁻²
Power = work / time
= 196,000 kgm²s⁻² / 5 seconds
= 39,000 kgm²s⁻³
