Answer: E = 39.54 N/C
Explanation: Electric field can be determined using surface charge density:
where:
σ is surface charge density
is permitivitty of free space ()
Calculating resulting electric field:
E = 39.54
The resulting Electric Field at any point is 39.54N/C.
Answer:
a) 19.1s
b) 599.4m
c) 62.8 m/s
Explanation:
Suppose both the officer and your good friend start at the same position (the intersection point). The equation of motion for each of them are:
- Your friend:
- The Officer:
(a) In order for the officer to catch him, they should both end up in the same position at the same time (other than t = 0)
(b) Within 19.1 s, the officer would have travelled a distance of
(c) His speed when he catches up would be
Answer:
Gamma rays
Explanation:
The penetrating power of gamma rays is maximum as compared to beta and alpha rays. Gamma rays are nothing but the photons i.e. the packets of energy. Their energy range lies from kilo electron volts to 8 mega electron volts. It is emitted during the decay of many radioactive isotopes, such as U-238 and I-131. A large amount of energy is produced in decay of uranium 238.
Hence, the correct option is " gamma rays ".
