Answer: 9kgm/s
Explanation:
Given that,
Mass of ball = 3 kg
Speed by which ball moves = 3 m/s. Linear momentum of the ball = ?
Since momentum refers to the quantity of motion of the moving ball,
Linear momentum = Mass x Speed
= 3kg x 3m/s
= 9 kgm/s
Thus, the linear momentum of the ball is 9kgm/s
Calculation, add them. 0.85 x 5 = 4.25 Ω
Use the law of conservation of charge: charge is always conserved. Here the system is the two balls, then the total initial charge of the two balls is the same of the total final charge of the two balls, which is +3.9 uC + 16.4 uC = +20.3uC.
When the balls are in contact, they behave as one alone piece and the total charge is evenly distributed among the whole surface. Given that the two balls are identical (same shape and same size) every ball support half of the charge.
Then, when the two balls are separated again each will have (+20.3 / 2) uC = 10.15 uC
