Explanation:

a)14.17V

b)32.8 x J

c)96.9x J

d) -64x J

Explanation:

Given:

Area 'A'=7.10cm² =>7.1 x m²

voltage ''=4.8 volt

= 2.20mm => 2.2 x m

= 6.50mm => 6.5 x m

a) Capacitance before push is given by:

= εA/ =>

=   2.85 x F

==> 2.85 x x 4.8

=1.37 x C

Capacitance after push is given by:

= εA/ =>

=   9.66 x F

=

=

Therefore, the potential difference between the plates

= 1.37 x / 9.66 x =>14.17V

b)

32.8 x J

c)

= 96.9x J

d) the work required to separate the plates is given by:

workdone=  -=> 32.8 x J- 96.9x J

W≈ -64x J
