Answer
The driver should reduce the speed or velocity of vehicle
because momentum which is
Mass x velocity will be reduced if velocity reduces and reduce force if impact
Answer:
![r =3 *\sqrt{2} = 4.24 cm](https://tex.z-dn.net/?f=r%20%3D3%20%2A%5Csqrt%7B2%7D%20%3D%204.24%20cm)
Explanation:
given data
Radius of sphere 3.0 cm
charge Q = 2.0 m C
We know that maximum electric field is given as
![E_{MAX}= \frac{KQ}{r^{2}}](https://tex.z-dn.net/?f=E_%7BMAX%7D%3D%20%5Cfrac%7BKQ%7D%7Br%5E%7B2%7D%7D)
electric field inside the sphere can be determine by using below relation
![\frac{KQ}{r^{2}}= \frac{1}{2}*\frac{KQ}{R^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7BKQ%7D%7Br%5E%7B2%7D%7D%3D%20%5Cfrac%7B1%7D%7B2%7D%2A%5Cfrac%7BKQ%7D%7BR%5E%7B2%7D%7D)
![r = \sqrt{2}R](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B2%7DR)
![r =3 *\sqrt{2} = 4.24 cm](https://tex.z-dn.net/?f=r%20%3D3%20%2A%5Csqrt%7B2%7D%20%3D%204.24%20cm)

Answer:
Explanation:
In a rotating system , when a torque is applied , angular acceleration or deceleration takes place . The child is walking towards the center . He must be applying force on the ground . In return , ground must be applying reaction force on him which helps him to go towards the center . These two force of action and reaction are internal forces . One will increase the angular momentum of one and the other force will decrease the angular
momentum of other . But total angular momentum of the whole system will remain constant . So angular momentum will be conserved.
