Answer:
Maximum charge will be
Explanation:
We have given force ion the moving charge
Maximum speed of the moving charge v = 30 m /sec
Magnetic field
We have to fond the charge
Force on moving charge is given by
So
Maximum charge will be

Answer:
0.014s
Explanation:
Given parameters:
mass of golf ball = 0.059kg
force applied = 290N
velocity = 69m/s
initial velocity = 0m/s
Unknown:
Time of contact = ?
Solution;
We know that momentum is the quantity of motion of body possess;
Momentum = mass x velocity
Momentum = 0.059 x 69 = 4.1kgm/s
Also; impulse is the effect of the force acting on a body;
impulse = force x time = momentum
So;
Force x time = momentum
Time = =
= 0.014s
