Correct answer is B
F = m (v-u)
= kg x m x S-2
= M1L1T-2
greater than the work function
less than the work function
equal to the work function
equal to the maximium kinetic energy of the electron
Correct answer is A

3.0 x 10-4J
3.0 x 10-1J
9.0 x 104J
9.0 x 1010J
Correct answer is D
Energy = mc2
= 1 x (3 x 108)2 x 106
= 9 x 1010J
6.5 x 10-2kg
2.6 x 10-2kg
6.5 x 10-3kg
2.6 x 10-3kg
Correct answer is D
m = QZ
= 2 x 104 x 1.3 x 10-7
= 2.6 x 10-3kg
0.625A
1.600A
2.500A
6.250A
Correct answer is A
Efficiency = \(\frac{I_sV_s}{I_pV_p}\) x 100
