Answer:
PART A)
External force will be 75 N
PART B)
distance moved will be 1.125 m
Explanation:
PART A)
Given that net force on the mower is
now we also know that friction force due to ground is given as
now we have
so external force will be 75 N
PART B)
deceleration due to friction when external force is removed from it
now we can find the distance by kinematics
so the distance moved will be 1.125 m

Answer:
V = 346.15 Volts
Explanation:
Given that,
Diameter of the sphere, d = 0.390 cm
Radius, r = 0.195 cm
Charge,
The electric potential near its surface is given by :
So, the potential near its surface is equal to 346.15 V.
